+<p>
+<b>12 SEPTEMBER 2011:</b> The PostgreSQL Global Development Group announces the release of PostgreSQL 9.1. This latest version of the leading open source database offers innovative technology, unmatched extensibility, and new features such as synchronous replication, K-Nearest Neighbor indexing, and foreign data wrappers.
+</p><p>
+"PostgreSQL 9.1 provides some of the most advanced enterprise capabilities of any open source database, and is backed by a vibrant and innovative community with proven customer success. PostgreSQL is well positioned for building and running applications in the cloud," said Charles Fan, Sr. VP R&D, VMware.
+</p><p>
+<h3>Responding to Users</h3>
+<p>
+Version 9.1 delivers several features which users have been requesting for years, removing roadblocks to deploying new or ported applications on PostgreSQL. These include:
+</p><ul>
+<li><b>Synchronous Replication</b>: enable high-availability with consistency across multiple servers</li>
+<li><b>Per-Column Collations</b>: support linguistically-correct sorting per database, table or column.</li>
+<li><b>Unlogged Tables</b>: greatly improves performance for ephemeral data</li>
+</ul><p>
+"Heroku runs the largest PostgreSQL database-as-a-service in the world," said James Lindenbaum, Heroku co-founder. "The release of synchronous data replication with 9.1 provides our customers with innovative new ways of protecting mission-critical data, and validates PostgreSQL as one of the fastest-moving datastores available."
+</p>
+<h3>Advancing the State of the Art</h3>
+<p>
+Our community of contributors innovates with cutting-edge features. Version 9.1 includes several which are new to the database industry, such as:
+</p><ul>

+<li><b>Writeable Common Table Expressions</b>: execute complex multi-stage data updates in a single query</li>
+<li><b>Security-Enhanced Postgres</b>: deploy military-grade security and Mandatory Access Control</li>
+</ul><p>
+"OpenERP has always relied on the enterprise-class features of PostgreSQL to provide a fast, reliable and scalable foundation for the Business Applications supporting our customers' operations every day. Data integrity in highly concurrent and transactional contexts is a critical topic for us, and we're very enthusiastic about the new Serializable Snapshot Isolation of PostgreSQL 9.1!" said Olivier Dony, OpenERP Community Manager.
+</p>
+<h3>Extending the Database Engine</h3>
+<p>
+PostgreSQL's extensibility enables users to add new functionality to a running production database, and use them for tasks no other database system can perform. Version 9.1 adds new extensibility tools, including:
+</p><ul>
+<li><b>Foreign Data Wrappers</b>: attach and query other databases from PostgreSQL</li>
+<li><b>Extensions</b>: easily create, load, and manage new database features</li>
+</ul>
+All of the above features, and more, are detailed on the <a href="http://wiki.postgresql.org/wiki/What%27s_new_in_PostgreSQL_9.1">What's New In 9.1</a> wiki page, as well as our <a href="http://www.postgresql.org/documentation/current/static/release-9-1">release notes</a>.

+<h2>Extended Release Information</h2>
+
+<a name="features"></a><h2>Details of Features</h2>
+
+<h3>Responding to Users</h3>
+<p>
+Version 9.1 delivers several features which users have been requesting for years, removing roadblocks to deploying new or ported applications on PostgreSQL. These include:
+</p><dl>
+<dt><b>Synchronous Replication for Clustering:</b></dt><dd> Enable high-availability with consistency across multiple nodes, by deploying PostgreSQL clusters using synchronous replication. Synchronous replication supports "2-safe replication" which ensures transactions have been confirmed by a standby server in addition to the master, greatly limiting the possibility of data loss. Only PostgreSQL has transaction-level synchronous replication, allowing users to choose per transaction between response time and data safety.</dd>
+<dt><b>Per-column Collations for Multi-lingual Databases:</b></dt><dd> Users can now set the collation for strings on a single column. This permits true multilingual databases, where each text column is a different language, and indexes and sorts correctly for that language.</dd>
+<dt><b>Unlogged Tables to Improve Performance:</b></dt><dd> When performance is more important than durability, unlogged tables provide a way to improve performance while keeping the data managed within PostgreSQL. Removing logging reduces I/O overhead, yielding performance improvements up to 10 times faster when compared to logged tables. Scenarios expected to leverage unlogged tables include web session data, real time logging, ETL and temporary/intermediate tables for functions.</dd>
+</dl>
+<h3>Advancing the State of the Art</h3>
+<p>
+Our community is innovating, delivering cutting-edge features which are new to the database industry. Some of these features are only available on PostgreSQL.
+</p><dl>
+<dt><b>Powerful Similarity Searches with K-Nearest-Neighbor (KNN) Indexing:</b></dt><dd> Create new applications using PostgreSQL KNN-GiST indexes, which provide innovative indexing to avoid expensive table scans. KNN enhances PostgreSQL's query capabilities by using mathematical "distance" for indexing and searches. These indexes can be used to enhance common text searches, text-similarity searches, geospatial location comparisons and other queries. Example searches that took 2 seconds without the index returned in 20 ms with this feature. Text search indexes can be also now be configured to provide indexing support for LIKE '%string%' queries without changing any SQL. PostgreSQL is among the first database systems to have KNN.</dd>
+<dt><b>Serializable Snapshot Isolation:</b></dt><dd> Allows users to enforce arbitrarily complex user-defined business rules within the database without blocking, by automatically detecting live race conditions in your SQL transactions at runtime. This feature currently exists only in PostgreSQL.</dd>
+<dt><b>Writeable Common Table Expressions (wCTE):</b></dt><dd> Supports the relational integrity of your data by allowing you to update multiple, cascading, related records in a single statement. By using the results of one query to execute another query, you can update recursively, hierarchically, across foreign keys, or even more creatively. PostgreSQL provides the most complete and flexible implementation of this SQL feature available.</dd>
+<dt><b>Security-Enhanced Postgres (SE-Postgres):</b></dt><dd> Deploy military-grade security and mandatory access control with full-integration support for Security-Enhanced Linux (SE-Linux). SE-Linux is a NSA project that modifies the Linux kernel with security-related functions. It has been endorsed by and included with major Linux distributions including, but not limited to, Red Hat, CentOS, Debian and Ubuntu. PostgreSQL is the only database system which has tight integration with SE-Linux.</dd>
+</dl>
+
+<h3>Extending the Database Engine</h3>
+<p>
+PostgreSQL's extensibility enables users to add new functionality to a running production database, and use them for tasks no other database system can perform. Version 9.1 adds critical new extensibility features, including:
+</p><dl>
+<dt><b>Foreign Data Wrappers (FDW):</b></dt><dd> As part of our standards-compliant SQL/MED support for querying data outside the PostgreSQL database, FDWs allow users to create "drivers" and attach external data sources, which can be used as read-only tables. FDWs make PostgreSQL a powerful tool for enterprise data integration, and they make migration easier. FDWs initially available from the community include comma-separated-value (CSV) files, Oracle, MySQL, CouchDB, and even Twitter sources. And many more are expected in the near future.</dd>
+<dt><b>Extensions:</b></dt><dd> While PostgreSQL has always been extensible, now users can easily create, load, upgrade, and manage any of dozens of database extensions using the EXTENSION database object. The new site PGXN.org offers a repository for contributing and downloading extensions.</dd>

+<a name="anniversary"></a><h2>25 Years of Database Innovation</a></h2>
+<p>
+The POSTGRES project was inaugurated at the University of California, Berkeley, in June 1986 with the publication of the original POSTGRES design by Lawrence A. Rowe and Michael R. Stonebraker. In the 25 years since then, POSTGRES became an open source project, converted to using SQL, changed its name to PostgreSQL, and became one of the leading relational databases. Today, our community competes with some of the largest software companies in the world to deliver new database functionality and better performance.
+</p><p>
+There have been 23 releases of POSTGRES and PostgreSQL, including version 9.1. PostgreSQL is the only major SQL database system to have consistent, featureful releases every year.

+<p>
+<b>12 SEPTEMBRE 2011 :</b> Le PostgreSQL Global Development Group annonce la publication de PostgreSQL 9.1.
+</p><p>
+Cette version du serveur de bases de données OpenSource de référence inclut une technologie innovante, un système d'extensions inégalé et des fonctionnalités nouvelles telles que la réplication synchrone, l'indexation des K-proches voisins et des conteneurs de données externes.
+</p><p>
+« PostgreSQL 9.1, fournit des possibilités professionnelles parmi les plus avancées de toutes les bases de données OpenSource. Le projet est épaulé par
+une communauté active et innovante aux succès clients éprouvés. PostgreSQL est très bien positionné pour la construction et l'exécution d'applications en
+cloud », déclare Charles Fan, Sr. VP R&D, VMWare.
+</p><p>
+<h3>Répondre aux utilisateurs</h3>
+<p>
+La version 9.1 délivre des fonctionnalités réclamées par les utilisateurs depuis de nombreuses années, supprimant ainsi les obstacles au déploiement d'applications nouvelles ou portées sous PostgreSQL. Cela inclut :
+
+</p><ul>
+<li><b>la réplication synchrone</b> : permet la haute-disponibilité par la cohérence sur plusieurs serveurs ;</li>
+<li><b>les collations de niveau colonne</b> : permettent des tri corrects au niveau linguistique, par base, table ou colonne ;</li>
+<li><b>les tables non tracées</b> : améliorent considérablement les performances des données éphémères.</li>
+</ul>
+<p>
+« Heroku fait tourner le plus grand database-as-a-service PostgreSQL au monde », déclare James Lindenbaum, co-fondateur d'Heroku. « La publication de la réplication synchrone des données avec la version 9.1 fournit à nos clients une voie innovante de protection des données critiques, et place PostgreSQL dans la liste des datastores les plus rapides. »
+</p>
+<h3>Faire progresser l'état de l'art</h3>
+<p>
+Notre communauté de contributeurs innove avec des fonctionnalités de pointe. La version 9.1 en inclut un grand nombre, nouvelles dans l'industrie des bases de données, telles que :
+</p><ul>
+<li><b>l'indexation K-plus-proche-voisin</b> : index sur la « distance » pour accélérer les requêtes de recherche de texte et de localisation ;</li>
+<li><b>l'isolation d'instantané sérialisable (Serializable Snapshot Isolation)</b> : conserve les transactions concurrentes cohérentes sans blocage, véritable sérialisation ;</li>
+<li><b>les expressions de tables communes enregistrables (Writeable Common Table Expressions)</b> : permet les actualisations complexes, en plusieurs étapes, de données en une seule requête ;</li>
+<li><b>une sécurité accrue</b> : permet de déployer une sécurité de niveau militaire et un contrôle obligatoire d'accès.</li>
+</ul><p>
+« OpenERP a toujours reposé sur les fonctionnalités de niveau entreprise de PostgreSQL pour fournir des fondations solides, rapides et extensibles sur lesquelles appuyer les applications professionnelles utilisées par nos clients chaque jour. L'intégrité des données dans des contextes transactionnels et concurrentiels est un sujet critique pour nous. Nous sommes, de ce fait, très enthousiastes à propos de l'isolation d'instantané sérialisable de PostgreSQL 9.1 ! », déclare Olivier Dony, responsable de la communauté OpenERP.
+</p>
+<h3>Étendre le moteur de base de données</h3>
+<p>
+L'extensibilité de PostgreSQL permet aux utilisateurs d'ajouter de nouvelles fonctionnalités à une base de données de production et de les utiliser pour réaliser des opérations qu'aucun autre système ne peut réaliser. La version 9.1 ajoute de nouveaux outils, dont :
+</p><ul>
+<li><b>des conteneurs de données externes</b> : qui permettent d'attacher et de requêter des bases différentes depuis PostgreSQL ;</li>
+<li><b>des extensions</b> : qui permettent de créer, charger, et gérer facilement de nouvelles fonctionnalités.</li>
+</ul>
+<p>
+Toutes les fonctionnalités précédentes, et bien plus encore, sont détaillées dans la page du Wiki <a href="http://wiki.postgresql.org/wiki/What%27s_new_in_PostgreSQL_9.1">« What's New In PostgreSQL 9.1 »</a>, dont une version français est disponible : <a href="http://wiki.postgresql.org/wiki/What%27s_new_in_PostgreSQL_9.1/fr">« Quoi de neuf dans PostgreSQL 9.1 »</a>. Les <a href="http://www.postgresql.org/documentation/current/static/release-9-1">notes de version</a> détaillent également toutes ces fonctionnalités.
+</p><p>
+Après 25 ans de développement du moteur, notre communauté continue de faire évoluer la technologie du moteur à chaque nouvelle version annuelle. Téléchargez la version 9.1 et vivez l'expérience du système de gestion de bases de données OpenSource de référence.
+</p><p>
+<b>À propos de PostgreSQL</b> :
+PostgreSQL est le système de gestion de bases de données OpenSource de référence. Sa communauté, mondiale, est composée de milliers d'utilisateurs et contributeurs, et de plusieurs dizaines de compagnies et institutions.
+Le projet PostgreSQL, démarré il y a 25 ans, à l'université de Californie, à Berkeley, a atteint aujourd'hui un rythme de développement sans pareil.
+L'ensemble des fonctionnalités matures a, non seulement, rejoint celui de systèmes commerciaux leaders, mais le dépasse même dans les fonctionnalités avancées, les extensions, la sécurité et la stabilité.

+<h2>Informations complémentaires</h2>
+
+<a name="features"></a><h3>Détail des fonctionnalités</h3>
+
+<h4>Répondre aux utilisateurs</h4>
+<p>
+La version 9.1 apporte des fonctionnalités réclamées par les utilisateurs depuis de nombreuses années, supprimant ainsi les obstacles au déploiement d'applications nouvelles ou portées sous PostgreSQL. Cela inclut :
+</p><dl>
+<dt><b>la réplication synchrone pour cluster</b> :</dt><dd> Permet la haute-disponibilité avec cohérence sur des nœuds multiples, en déployant des clusters PostgreSQL. La réplication synchrone (protocole « 2-safe ») assure que les transactions sont validées sur un serveur secondaire avant de l'être sur le primaire. Cela limite grandement les risques de pertes de données. PostgreSQL est le seul système à disposer de la réplication synchrone au niveau des transactions. L'utilisateur peut ainsi choisir entre temps de réponse et sécurisation des données à chaque transaction.</dd>
+<dt><b>les collations par colonne pour les bases multilingues</b> :</dt><dd> Les utilisateurs peuvent désormais définir la collation des chaînes sur une seule colonne. Cela autorise les véritables bases de données multilingues, pour lesquelles chaque colonne est dans une langue différente, avec des index et des tris adaptés à chaque langue.</dd>
+<dt><b>les tables non tracées pour améliorer les performances</b> :</dt><dd> Lorsque les performances sont plus importantes que la persistance, les tables non tracées permettent d'améliorer les performances tout en laissant PostgreSQL gérer les données. La suppression des traces réduit les temps d'accès disque, conduisant à des temps de réponse jusqu'à dix fois plus courts qu'avec des tables tracées. Les tables non-tracées sont intéressantes pour les données de session web, les enregistrements temps-réel, les ETL et les tables temporaires ou intermédiaires dans les fonctions.</dd>
+</dl>
+<h4>Faire progresser l'état de l'art</h4>
+<p>
+Notre communauté innove avec des fonctionnalités de pointe, nouvelles dans l'industrie des bases de données. Certaines ne sont disponibles qu'avec PostgreSQL.
+</p><dl>
+<dt><b>Recherche puissante de similarités avec l'indexation K-plus-proche-voisin (K-Nearest-Neighbor, KNN)</b> :</dt><dd> De nouvelles applications peuvent être créées par l'emploi des index KNN-GiST de PostgreSQL. Ceux-ci fournissent une indexation innovante évitant des parcours de tables coûteux. KNN améliore les possibilités de requêtage par l'utilisation de la « distance » mathématique pour les indexations et les recherches. Ces index peuvent être utilisés pour améliorer les recherches habituelles de texte, les recherches de similarités de texte, les comparaisons de localisations géospatiales et d'autres types de requêtes. Des exemples de recherche qui prenaient 2 secondes sans l'index sont descendus à 20ms à l'aide de cette fonctionnalité. Les index de recherche textuelle peuvent désormais être configurés pour indexer les requêtes de type LIKE '%chaine%', sans modification du SQL. PostgreSQL est l'un des premiers systèmes à proposer le KNN.</dd>
+<dt><b>Isolation d'instantanée sérialisable (Serializable Snapshot Isolation)</b> :</dt><dd> Permet aux utilisateurs d'appliquer des rêgles métier complexes au sein de la base sans blocage, en détectant automatiquement les conflits entre transactions SQL à l'exécution. Cette fonctionnalité n'existe actuellement qu'au sein de PostgreSQL.</dd>
+<dt><b>les expressions de tables communes enregistrables (Writeable Common Table Expressions, wCTE)</b> :</dt><dd> Assure l'intégrité relationnelle des données en permettant d'actualiser des enregistrements multiples, en cascade et liés, au sein d'une unique instruction. En utilisant les résultats d'une requête pour en exécuter une autre, il est possible d'effectuer des mises à jour récursives, hiérarchiques, au travers des clés étrangères, voire plus complexes encore. PostgreSQL est le moteur qui offre l'implantation la plus complète et la plus flexible de cette fonctionnalité SQL.</dd>
+<dt><b>Postgres à sécurité renforcée (Security-Enhanced Postgres, SE-Postgres)</b> :</dt><dd> Déployer une sécurité de niveau militaire et un contrôle d'accès par l'intégration de Security-Enhanced Linux (SE-Linux). SE-Linux est un projet de la NSA qui modifie le noyau Linux à l'aide de fonctions orientées sécurité. Soutenu par les plus grandes distributions et intégré aux distributions majeures, telles que Red Hat, CentOS, Debian et Ubuntu, pour en citer quelques-unes. PostgreSQL est le seul moteur a avoir une intégration aussi aboutie de SE-Linux.</dd>
+</dl>
+
+<h4>Étendre le moteur</h4>
+<p>
+L'extensibilité de PostgreSQL permet aux utilisateurs d'ajouter de nouvelles fonctionnalités à une base en production, et de les utiliser pour réaliser des tâches qu'aucun autre moteur ne peut réaliser. La version 9.1 ajoute de nouvelles fonctionnalités d'extension, dont :
+</p><dl>
+<dt><b>Les conteneurs de données externes (Foreign Data Wrappers, FDW)</b> :</dt><dd> Faisant partie de SQL/MED pour interroger des données extérieures à la base PostgreSQL, ces conteneurs permettent de créer des « pilotes » et d'attacher des données externes, qui peuvent être utilisées comme tables en lecture seule. Les conteneurs font de PostgreSQL un outil puissant pour l'intégration de données d'entreprise, et facilitent leur migration. Les conteneurs, issus de la communauté, incluent des sources telles que des fichiers au format CSV, Oracle, MySQL, CouchDB, et même Twitter. D'autres sources sont attendues.</dd>
+<dt><b>Extensions</b> :</dt><dd> Bien que PostgreSQL ait toujours été extensible, les utilisateurs peuvent désormais facilement créer, charger, mettre à jour et gérer des douzaines d'extensions à partir de l'objet EXTENSION. Le nouveau site PGXN.org offre un dépôt pour contribuer et télécharger les extensions.</dd>

+Le projet POSTGRES a été inauguré à l'Université de Californie, Berkeley, en juin 1986 avec la publication du descriptif original de POSTGRES par Lawrence A. Rowe et Michael R. Stonebraker. Dans les 25 années qui ont suivi, POSTGRES est devenu un projet libre, a été converti au SQL, a changé de nom pour devenir PostgreSQL, et est devenu un des moteurs relationnels de références. Aujourd'hui notre communauté rivalise avec quelques-unes des plus grosses compagnies mondiales d'édition de logiciels pour fournir de nouvelles fonctionnalités de bases de données et améliorer les performances.
+</p><p>
+Il y a eu 23 versions de POSTGRES et PostgreSQL avec la version 9.1. PostgreSQL est la seule base majeure à proposer des versions complètes et cohérentes chaque année.

+HOW TO USE GIT FOR RELEASE TRANSLATION
+
+This year there are only two ways to submit your translations for the 9.1 Release: email, and Git on git.postgresql.org. Of these two, Git is preferred because:
+
+- You can version-control your own work
+- You can use it to do version control between multiple translators
+- Your translated documents won't get mangled by email servers
+
+Also, since Git is now the version control system for developing PostgreSQL, you might as well learn it.
+
+1. Community Account
+--------------------
+In order to use the git repo, you need a PostgreSQL.org community account. This is the same account you use on www.postgresql.org, planet.postgresql.org, and several other places (but not pgfoundry). If you do not already have one, obtain one here:
+
+http://www.postgresql.org/community/signup
+
+Once you have a community account, email Josh Berkus (josh@agliodbs.com) so that he can grant you write access to git.postgresql.org/press.
+
+2. Install Git
+--------------
+While you're waiting for your community account with Git access, please install Git on your workstation/laptop if you don't already have it. On Linux or FreeBSD this is simple through your packaging system. On Mac OSX, you should use Fink (http://www.finkproject.org/) or MacPorts (http://www.macports.org/) to install Git, or the DMG here: http://code.google.com/p/git-osx-installer/. For Windows users, there is a list of suggested Git clients here: http://kylecordes.com/2010/git-gui-client-windows and a help guide here: http://help.github.com/win-set-up-git/
+
+3. Clone Git Repo
+-----------------
+From the command line, switch to a directory where you want to work with the PR files. Then do:
+
+git clone git://git.postgresql.org/git/press.git
+
+This will make a full copy of the press repository, including the last several sets of release translations. It make take a few minutes.
+
+4. Create Directories
+---------------------
+You will be adding your translated versions to the directory press/releases/9.1/xx, where "xx" is your two-letter ISO language code. For example, if you're translating Portuguese, then add this directory:
+
+press/releases/9.1/pt
+
+5. Translate the Release
+------------------------
+Translate both files, presskit91.html and release.txt. Create the translated versions as presskit91.html and release.txt in your language directory (not, for example, presskit91.html.pt).
+
+NOTE: last year we tried creating a git branch for each language. This did not work well. So please make all of your edits on the "master" branch. Also, please be careful to edit ONLY files in your language directory in order to prevent making conflicting edits.
+
+6. Commit and Push
+------------------
+First, from your language directory, do:
+
+git add *
+
+Then do:
+
+git commit -a
+
+This will bring up your default text editor to write a commit message. Please indicate in the commit message whether or not this is the final completed translation of your release and presskit, so I know when you're done.
+
+Finally, you need to sync your local copy with the git.postgresql.org server, with:
+
+git push
+
+7. Repeat if Necessary
+----------------------
+If you are translating in several sessions, or coordinating with other volunteers with your same language, then you should do several commits and pushes. Do these as often as you like.
+
+8. Final Commit & Push
+----------------------
+When you are completely done translating the presskit and release, then do a final commit and push with a commit message like:
+
+"Translation of release and presskit for DE completed."
+
+This will let me know when you're done translating.
+
+9. If you run into trouble
+--------------------------
+Ask for help on the translators@postgresql.org mailing list.

+<a name="original_release"></a><h2>Original Press Release</h2>
+<p>
+<b>12 SEPTEMBER 2011:</b> The PostgreSQL Global Development Group announces the release of PostgreSQL 9.1. This latest version of the leading open source database offers innovative technology, unmatched extensibility, and new features such as synchronous replication, K-Nearest Neighbor indexing, and foreign data wrappers.
+</p><p>
+"PostgreSQL 9.1 provides some of the most advanced enterprise capabilities of any open source database, and is backed by a vibrant and innovative community with proven customer success. PostgreSQL is well positioned for building and running applications in the cloud," said Charles Fan, Sr. VP R&D, VMware.
+</p><p>
+<h3>Responding to Users</h3>
+<p>
+Version 9.1 delivers several features which users have been requesting for years, removing roadblocks to deploying new or ported applications on PostgreSQL. These include:
+</p><ul>
+<li><b>Synchronous Replication</b>: enable high-availability with consistency across multiple servers</li>
+<li><b>Per-Column Collations</b>: support linguistically-correct sorting per database, table or column.</li>
+<li><b>Unlogged Tables</b>: greatly improves performance for ephemeral data</li>
+</ul><p>
+"Heroku runs the largest PostgreSQL database-as-a-service in the world," said James Lindenbaum, Heroku co-founder. "The release of synchronous data replication with 9.1 provides our customers with innovative new ways of protecting mission-critical data, and validates PostgreSQL as one of the fastest-moving datastores available."
+</p>
+<h3>Advancing the State of the Art</h3>
+<p>
+Our community of contributors innovates with cutting-edge features. Version 9.1 includes several which are new to the database industry, such as:
+</p><ul>
+<li><b>K-Nearest-Neighbor Indexing</b>: index on "distance" for faster location and text-search queries</li>
+<li><b>Serializable Snapshot Isolation</b>: keeps concurrent transactions consistent without blocking, using "true serializability"</li>
+<li><b>Writeable Common Table Expressions</b>: execute complex multi-stage data updates in a single query</li>
+<li><b>Security-Enhanced Postgres</b>: deploy military-grade security and Mandatory Access Control</li>
+</ul><p>
+"OpenERP has always relied on the enterprise-class features of PostgreSQL to provide a fast, reliable and scalable foundation for the Business Applications supporting our customers' operations every day. Data integrity in highly concurrent and transactional contexts is a critical topic for us, and we're very enthusiastic about the new Serializable Snapshot Isolation of PostgreSQL 9.1!" said Olivier Dony, OpenERP Community Manager.
+</p>
+<h3>Extending the Database Engine</h3>
+<p>
+PostgreSQL's extensibility enables users to add new functionality to a running production database, and use them for tasks no other database system can perform. Version 9.1 adds new extensibility tools, including:
+</p><ul>
+<li><b>Foreign Data Wrappers</b>: attach and query other databases from PostgreSQL</li>
+<li><b>Extensions</b>: easily create, load, and manage new database features</li>
+</ul>
+All of the above features, and more, are detailed on the <a href="http://wiki.postgresql.org/wiki/What%27s_new_in_PostgreSQL_9.1">What's New In 9.1</a> wiki page, as well as our <a href="http://www.postgresql.org/documentation/current/static/release-9-1">release notes</a>.
+</p><p>
+In PostgreSQL's 25th year of database development, our community continues to advance database technology with every annual release. Download version 9.1 now and experience the most advanced open source database system in the world.
+</p><p>

+
+<h2>Extended Release Information</h2>
+
+<a name="features"></a><h2>Details of Features</h2>
+
+<h3>Responding to Users</h3>
+<p>
+Version 9.1 delivers several features which users have been requesting for years, removing roadblocks to deploying new or ported applications on PostgreSQL. These include:
+</p><dl>
+<dt><b>Synchronous Replication for Clustering:</b></dt><dd> Enable high-availability with consistency across multiple nodes, by deploying PostgreSQL clusters using synchronous replication. Synchronous replication supports "2-safe replication" which ensures transactions have been confirmed by a standby server in addition to the master, greatly limiting the possibility of data loss. Only PostgreSQL has transaction-level synchronous replication, allowing users to choose per transaction between response time and data safety.</dd>
+<dt><b>Per-column Collations for Multi-lingual Databases:</b></dt><dd> Users can now set the collation for strings on a single column. This permits true multilingual databases, where each text column is a different language, and indexes and sorts correctly for that language.</dd>
+<dt><b>Unlogged Tables to Improve Performance:</b></dt><dd> When performance is more important than durability, unlogged tables provide a way to improve performance while keeping the data managed within PostgreSQL. Removing logging reduces I/O overhead, yielding performance improvements up to 10 times faster when compared to logged tables. Scenarios expected to leverage unlogged tables include web session data, real time logging, ETL and temporary/intermediate tables for functions.</dd>
+</dl>
+<h3>Advancing the State of the Art</h3>
+<p>
+Our community is innovating, delivering cutting-edge features which are new to the database industry. Some of these features are only available on PostgreSQL.
+</p><dl>
+<dt><b>Powerful Similarity Searches with K-Nearest-Neighbor (KNN) Indexing:</b></dt><dd> Create new applications using PostgreSQL KNN-GiST indexes, which provide innovative indexing to avoid expensive table scans. KNN enhances PostgreSQL's query capabilities by using mathematical "distance" for indexing and searches. These indexes can be used to enhance common text searches, text-similarity searches, geospatial location comparisons and other queries. Example searches that took 2 seconds without the index returned in 20 ms with this feature. Text search indexes can be also now be configured to provide indexing support for LIKE '%string%' queries without changing any SQL. PostgreSQL is among the first database systems to have KNN.</dd>
+<dt><b>Serializable Snapshot Isolation:</b></dt><dd> Allows users to enforce arbitrarily complex user-defined business rules within the database without blocking, by automatically detecting live race conditions in your SQL transactions at runtime. This feature currently exists only in PostgreSQL.</dd>
+<dt><b>Writeable Common Table Expressions (wCTE):</b></dt><dd> Supports the relational integrity of your data by allowing you to update multiple, cascading, related records in a single statement. By using the results of one query to execute another query, you can update recursively, hierarchically, across foreign keys, or even more creatively. PostgreSQL provides the most complete and flexible implementation of this SQL feature available.</dd>
+<dt><b>Security-Enhanced Postgres (SE-Postgres):</b></dt><dd> Deploy military-grade security and mandatory access control with full-integration support for Security-Enhanced Linux (SE-Linux). SE-Linux is a NSA project that modifies the Linux kernel with security-related functions. It has been endorsed by and included with major Linux distributions including, but not limited to, Red Hat, CentOS, Debian and Ubuntu. PostgreSQL is the only database system which has tight integration with SE-Linux.</dd>
+</dl>
+
+<h3>Extending the Database Engine</h3>
+<p>
+PostgreSQL's extensibility enables users to add new functionality to a running production database, and use them for tasks no other database system can perform. Version 9.1 adds critical new extensibility features, including:
+</p><dl>
+<dt><b>Foreign Data Wrappers (FDW):</b></dt><dd> As part of our standards-compliant SQL/MED support for querying data outside the PostgreSQL database, FDWs allow users to create "drivers" and attach external data sources, which can be used as read-only tables. FDWs make PostgreSQL a powerful tool for enterprise data integration, and they make migration easier. FDWs initially available from the community include comma-separated-value (CSV) files, Oracle, MySQL, CouchDB, and even Twitter sources. And many more are expected in the near future.</dd>
+<dt><b>Extensions:</b></dt><dd> While PostgreSQL has always been extensible, now users can easily create, load, upgrade, and manage any of dozens of database extensions using the EXTENSION database object. The new site PGXN.org offers a repository for contributing and downloading extensions.</dd>

+<p>
+The POSTGRES project was inaugurated at the University of California, Berkeley, in June 1986 with the publication of the original POSTGRES design by Lawrence A. Rowe and Michael R. Stonebraker. In the 25 years since then, POSTGRES became an open source project, converted to using SQL, changed its name to PostgreSQL, and became one of the leading relational databases. Today, our community competes with some of the largest software companies in the world to deliver new database functionality and better performance.
+</p><p>
+There have been 23 releases of POSTGRES and PostgreSQL, including version 9.1. PostgreSQL is the only major SQL database system to have consistent, featureful releases every year.

This latest version of the leading open source database offers new features, innovative technology, and extensibility such as synchronous replication, K-Nearest Neighbor indexing, and foreign data wrappers.
+
+“PostgreSQL 9.1 provides some of the most advanced enterprise capabilities of any open source database, and is backed by a vibrant and innovative community with proven customer success. PostgreSQL is well positioned for building and running applications in the cloud,” said Charles Fan, Sr. VP R&D, VMware.
+
+Responding to Users
+
+Version 9.1 delivers several features which users have been requesting for years, removing roadblocks to deploying new or ported applications on PostgreSQL. These include:
+
+- Synchronous Replication for Clustering: enable high-availability with consistency
+- Per-Column Collations: support linguistically-correct sorting per database, table or column.
+- Unlogged Tables: greatly improves performance for ephemeral data
+
+"Heroku runs the largest PostgreSQL database-as-a-service in the world," said James Lindenbaum, Heroku co-founder. "The release of synchronous data replication with 9.1 provides our customers with innovative new ways of protecting mission-critical data, and validates PostgreSQL as one of the fastest-moving datastores available."
+
+Advancing the State of the Art
+
+Our community of contributors is innovating, delivering cutting-edge features which are new to the database industry. Some of these features are only available on PostgreSQL.
+
+- K-Nearest-Neighbor Indexing: index on "distance" for faster spatial and text-search queries
+- Serializable Snapshot Isolation: implements "true serializability" without blocking
+- Writeable Common Table Expressions: execute complex multi-stage data updates in a single query
+- Security-Enhanced Postgres: deploy military-grade security and mandatory access control
+
+"OpenERP has always relied on the enterprise-class features of PostgreSQL to provide a fast, reliable and scalable foundation for the Business Applications supporting our customers' operations every day. Data integrity in highly concurrent and transactional contexts is a critical topic for us, and we're very enthusiastic about the new Serializable Snapshot Isolation of PosgtreSQL 9.1!" said Olivier Dony, OpenERP Community Manager.
+
+Extending the Database Engine
+
+PostgreSQL's extensibility enables users to add new functionality to the database at runtime and use it for tasks no other database system can perform. Version 9.1 adds critical new extensibility features, including:
+
+- Foreign Table Wrappers: attach and query other databases from PostgreSQL
+- Extensions: easily create, load, and manage any of dozens of database extensions
+
+All of the above features, and more, are detailed on the What's New In 9.1 wiki page, as well as our release notes.
+

+\r
+<a name="features"></a><h2>新特性列表</h2>\r
+\r
+<h3>对用户要求的响应</h3>\r
+<p>\r
+9.1版本增加了几项用户一直以来申请增加的功能，为用户在PostgreSQL基础上发布新的应用扫清了障碍，这些功能包括：\r
+</p><dl>\r
+<dt><b>集群的同步复制:</b></dt><dd> 通过布置使用同步复制技术的PostgreSQL集群，允许跨多服务器节点进行高可靠性复制。同步复制支持“２路安全复制”技术，该技术通过主服务器和额外的备份服务器保证事务的确认，极大地减少了数据损失的发生风险。目前仅PostgreSQL支持事务级的同步复制，这项技术允许用户在响应时间和数据安全方面根据事务进行选择。</dd>\r
+<dt><b>可按字段级控制的多编码数据库:</b></dt><dd> 用户现在可对某一字段设置不同的字符编码，这样才是真正的允许多编码数据库，每一字段可以有不同的编码，索引和排序也相应地参照这个编码执行。</dd>\r
+<dt><b>高性能的非日志型表:</b></dt><dd> 当用户对性能要求高于稳定性时，非日志型表提供了一个方式允许用户在PostgreSQL中以高性能的方式管理和操作数据。它可以减少了I/O的操作，相比日志型数据表提高了10倍以上的速度。该技术适用于session数据、实时日志、ETL以及其他需临时/中间记录等一些功能。</dd>\r
+</dl>\r
+<h3>（艺术级）的高级功能</h3>\r
+<p>\r
+我们社区的开发人员创新地开发了几项最前沿的功能，9.1版本包括以下几项数据库业界全新的功能，如：\r
+</p><dl>\r
+<dt><b>强大的相似性搜索（KNN索引）:</b></dt><dd> 使用PostgreSQL KNN-Gist索引创建一个新的应用可以避免费用的数据表扫描。通过使用数学上的“距离”计算用于索引和搜索，KNN技术增强了PostgreSQL的查询能力。这些索引可用于增强一般的文字搜索、文本相似性搜索、地理空间位置比较和其他查询。在一个无索引的表搜索中，不使用KNN功能搜索需花2秒，而使用后仅需20ms。文字搜索经过配置在不改变任何SQL语句的情况下，也可以支持类似 LIKE '%string%'样的查询。PostgreSQL是业界内第一个使用KNN技术的数据库系统。</dd>\r
+<dt><b>可串行化的快照隔离:</b></dt><dd> 通过在事务运行时自动侦测已使用的冲突条件来允许用户强制多次地执行复杂的用户自定义的商业规则而不会有阻隔。这个功能目前也是仅PostgreSQL具有。</dd>\r
+<dt><b>可更新的CTE功能 (wCTE):</b></dt><dd> 支持用户在一个语句内执行多个、级联、相关记录的更新。通过使用一个查询的结果去执行另一个查询，用户可以递归地、分级地、跨外键地或是更加创新的方式来更新数据。PostgreSQL为这项SQL特性提供了一个最为完整和有灵活性解决方案。</dd>\r
+<dt><b>安全增强型版本 (SE-Postgres):</b></dt><dd> 通过与SE-Linux的全集成，发布军队安全级和强制存取控制的版本。SE-Linux是通过修改Linux核心来强化安全相关功能的NSA项目。它现已支持主要的Linux发布版本，包括但不限于Red Hat, CentOS, Debian 和 Ubuntu。PostgreSQL是唯一与SE-Linux集成的数据库系统。</dd>\r
+</dl>\r
+\r
+<h3>可扩展的数据库引擎</h3>\r
+<p>\r
+PostgreSQL的可扩展性允许用户增加新的功能来运行生产环境的数据库，并且可以执行一些其他数据库系统无法完成的任务，9.1版本增加的新可扩展性工具，包括：\r
+ \r
+</p><dl>\r
+<dt><b>外部数据源封装器 (FDW):</b></dt><dd> 为了查询PostgreSQL数据库之外数据，作为SQL/MED标准兼容的一项功能，FDW功能允许用户创建驱动程序连接外部数据源，这样这些数据就成为了PostgreSQL内部只读的表。FDW功能使PostgreSQL成为企业数据集成的一个强大工具，这也使得数据迁移很容易。FDW目前开始支持CSV格式文件、Oracle、MySQL、CouchDB、甚至还有Twitter数据源。更多的数据库支持最近也将提供。</dd>\r
+<dt><b>扩充功能:</b></dt><dd> 尽管PostgreSQL一直就有扩充功能，但现在用户通过使用EXTENSION功能可以更加容易地创建、加载、升级和管理一大堆数据库的扩展。 新的网站PGXN.org上提供了很多可下载的扩展模块。</dd>\r

+<p>\r
+POSTGRES项目起源于加利福利亚的伯克利大学，最早源于1986年6月发布的POSTGRES，它是由Lawrence A. Rowe 和 Michael R. Stonebraker设计的。从那以后的25年里，POSTGRES成为一个开源项目，转换为使用SQL，改其名称为PostgreSQL，并成为领先的关系数据库系统。今天，我们的社区在开发新的数据库功能以及提升性能方面可以和一些世界上最大的软件公司相媲美。\r
+</p><p>\r
+包括9.1版本，POSTGRES 和 PostgreSQL共发布了23个大的版本。PostgreSQL是仅有的可以持续每年发布新的大版本的主要数据库软件。\r
