<h1>Frequently Asked Questions</h1>
<p><b>Q: What is the current version of PostgreSQL?</b><br />
-A: 9.4, which was released December 18, 2014.</p>
+A: 9.5, which was released January 7, 2016.</p>
-<p><b>Q: 9.4? Does that mean it's a minor release?</b><br />
-A: No, it's approximately our 25th major release in 28 years of development. We release a new version of PostgreSQL every year, which is unique among SQL databases. Because of the long history of our project the first two decimals are major releases. Thus 9.4, 9.1 and 9.0 were all major releases. Minor releases have numbers like 9.2.9. This is similar to how Linux, Apache, and MySQL number their versions.</p>
+<p><b>Q: 9.5? Does that mean it's a minor release?</b><br />
+A: No, it's approximately our 26th major release in 29 years of development. We release a new version of PostgreSQL every year, which is unique among SQL databases. Because of the long history of our project the first two decimals are major releases. Thus 9.5, 9.1 and 9.0 were all major releases. Minor releases have numbers like 9.2.9. This is similar to how Linux, Apache, and MySQL number their versions.</p>
<p><b>Q: How is PostgreSQL licensed? How much does it cost?</b><br />
A: PostgreSQL is released under the OSI-approved PostgreSQL License. There is no fee, even for use in commercial software products. Please see <a href="/about/licence">the PostgreSQL License</a></p>
<p><b>Q: Where can people get support for PostgreSQL?</b><br />
A: There are several companies which provide paid support for PostgreSQL. Most of them are regional in nature. People should contact the nearest regional contact volunteer to be connected with one or more companies, or check our <a href="/support/professional_support/">professional services list</a>.</p>
-<p><b>Q: What's the relationship between the PostgreSQL Project, EnterpriseDB, 2ndQuadrant, CommandPrompt, SRA, Heroku, VMWare and others?</b><br />
+<p><b>Q: What's the relationship between the PostgreSQL Project, EnterpriseDB, 2ndQuadrant, CommandPrompt, SRA, Heroku, Crunchy Data and others?</b><br />
A: The PostgreSQL project enjoys the support of multiple companies who sell products or services built with PostgreSQL, and in turn contribute code, money and staff time to the project. None of them "own" PostgreSQL, nor is any individual company responsible for PostgreSQL code development. This is the same as Linux, Apache and FreeBSD.</p>
<p><b>Q: Does PostgreSQL run on the Cloud?</b><br />
A: To date there is one: a <a href="http://www.spec.org/jAppServer2004/results/res2007q3/jAppServer2004-20070703-00073.html">SpecJAppserver2004 benchmark</a>, which at time of publication was within 10% of the leading commercial SQL RDBMS. We are not certain when another benchmark will be published, as verifiable benchmarks are expensive and time-consuming for a not-for-profit community to undertake.</p>
<p><b>Q: When will PostgreSQL get database server clustering?</b><br />
-A: We already have it. Since no one type of clustering satisfies all needs, we have several different clustering tools which take various clustering approaches. The open source projects PostgresXC, Postgres-XL, Stado and pgPool2 are available, as well as proprietary tools such as Translattice, Greenplum Database, Aster Data, CitusData and several others. Also, PostgreSQL is supported by filesystem-based clustering systems for failover, including ones from Red Hat, Microsoft, Veritas and Oracle.</p>

Also, PostgreSQL is supported by filesystem-based clustering systems for failover, including ones from Red Hat, Microsoft, Veritas and Oracle.</p>
<p><b>Q: Has PostgreSQL won any awards?</b><br />
A: Several. Most recently, we won <a href="http://www.developer.com/design/article.php/10925_3721761_1">the 2008 Developer.com Award for best Database Tool</a>. Other awards we've won over the years are
listed on our <a href="/about/awards">awards page</a>.
</p>
-<p><b>Q: When will 9.5 come out?</b><br />
-A: The PostgreSQL project begins work on the next version of PostgreSQL in July of each year, and it generally takes 12 to 15 months to work to a release. So expect 9.5 around September 2015. We are the only major SQL database which releases every year.</p>

-<p><b>Q: What features will 9.5 have?</b><br />
-A: As always, we can't be certain what will go in and what won't; the project has strict quality standards that not all patches can make before deadline. All we can tell you is what's being worked on, which includes: BRIN indexes for big data, new partitioning, OLAP CUBEs, UPSERT, and parallel VACUUM. By the time 9.5 is released, though, this feature list will have changed considerably.</p>

All we can tell you is what's being worked on, which includes: parallel sequential scan, federated/partitioned FDWs, pg_rewind integration, pluggable sequence generators, improved multcore scalability, bloom filter joins, multiple sequential replicas, built-in column storage, new partitioning, and more. By the time 9.6 is released, though, this feature list will have changed considerably.</p>
<p><b>Q: How do you pronounce PostgreSQL</b><br />
A: post-GRES-que-ell, per this <a href="/files/postgresql.mp3">audio file</a>. Many people, however, just say "post-GREZ".</p>

+
+<h2>PostgreSQL 9.5: UPSERT, Row Level Security, and Big Data Features</h2>
+<p>
+7 JANUARY 2016: The PostgreSQL Global Development Group announces the release of PostgreSQL 9.5. This release adds UPSERT capability, Row Level Security, and multiple Big Data features, which will broaden the user base for the world's most advanced database. With these new capabilities, PostgreSQL will be the best choice for even more applications for startups, large corporations, and government agencies.
+</p><p>
+Annie Prévot, CIO of the CNAF, the French Child Benefits Office, said, "The CNAF is providing services for 11 million persons and distributing 73 billion Euros every year, through 26 types of social benefit schemes. This service is essential to the population and it relies on an information system that must be absolutely efficient and reliable. The CNAF's information system is satisfyingly based on the PostgreSQL database management system."
+</p><p>
+<b>UPSERT</b>
+</p><p>
+A most-requested feature by application developers for several years, "UPSERT" is shorthand for "INSERT, ON CONFLICT UPDATE", allowing new and updated rows to be treated the same. UPSERT simplifies web and mobile application development by enabling the database to handle conflicts between concurrent data changes. This feature also removes the last significant barrier to migrating legacy MySQL applications to PostgreSQL.
+</p><p>
+Developed over the last two years by Heroku programmer Peter Geoghegan, PostgreSQL's implementation of UPSERT is significantly more flexible and powerful than those offered by other relational databases. The new ON CONFLICT clause permits ignoring the new data, or updating different columns or relations in ways which will support complex ETL (Extract, Transform, Load) toolchains for bulk data loading. And, like all of PostgreSQL, it is designed to be absolutely concurrency-safe and to integrate with all other PostgreSQL features, including Logical Replication.
+</p><p>
+<b>Row Level Security</b>
+</p><p>
+PostgreSQL continues to expand database security capabilities with its new Row Level Security (RLS) feature. RLS implements true per-row and per-column data access control which integrates with external label-based security stacks such as SE Linux. PostgreSQL is already known as "the most secure by default." RLS cements its position as the best choice for applications with strong data security requirements, such as compliance with PCI, the European Data Protection Directive, and healthcare data protection standards.
+</p><p>
+RLS is the culmination of five years of security features added to PostgreSQL, including extensive work by KaiGai Kohei of NEC, Stephen Frost of Crunchy Data, and Dean Rasheed. Through it, database administrators can set security "policies" which filter which rows particular users are allowed to update or view. Data security implemented this way is resistant to SQL injection exploits and other application-level security holes.
+</p><p>
+<b>Big Data Features</b>
+</p><p>
+PostgreSQL 9.5 includes multiple new features for bigger databases, and for integrating with other Big Data systems. These features ensure that PostgreSQL continues to have a strong role in the rapidly growing open source Big Data marketplace. Among them are:
+</p><p>
+<b>BRIN Indexing</b>: This new type of index supports creating tiny, but effective indexes for very large, "naturally ordered" tables. For example, tables containing logging data with billions of rows could be indexed and searched in 5% of the time required by standard BTree indexes.
+</p><p>
+<b>Faster Sorts</b>: PostgreSQL now sorts text and NUMERIC data faster, using an algorithm called "abbreviated keys". This makes some queries which need to sort large amounts of data 2X to 12X faster, and can speed up index creation by 20X.
+</p><p>
+<b>CUBE, ROLLUP and GROUPING SETS</b>: These new standard SQL clauses let users produce reports with multiple levels of summarization in one query instead of requiring several. CUBE will also enable tightly integrating PostgreSQL with more Online Analytic Processing (OLAP) reporting tools such as Tableau.
+</p><p>
+<b>Foreign Data Wrappers (FDWs)</b>: These already allow using PostgreSQL as a query engine for other Big Data systems such as Hadoop and Cassandra. Version 9.5 adds IMPORT FOREIGN SCHEMA and JOIN pushdown making query connections to external databases both easier to set up and more efficient.
+</p><p>
+<b>TABLESAMPLE</b>: This SQL clause allows grabbing a quick statistical sample of huge tables, without the need for expensive sorting.
+</p><p>
+"The new BRIN index in PostgreSQL 9.5 is a powerful new feature which enables PostgreSQL to manage and index volumes of data that were impractical or impossible in the past. It allows scalability of data and performance beyond what was considered previously attainable with traditional relational databases and makes PostgreSQL a perfect solution for Big Data analytics," said Boyan Botev, Lead Database Administrator, Premier, Inc.

+<h2>PostgreSQL 9.5: UPSERT, Row Level Security et Big Data</h2>
+<p>
+Cette version ajoute les capacités d'UPSERT, les droits de niveau ligne (Row Level Security), et de nombreuses fonctionnalités orientées Big Data, qui ouvrent plus grand encore les possibilités d'utilisation de PostgreSQL.
+Avec ces nouvelles fonctionnalités, PostgreSQL va devenir le choix par défaut pour un nombre encore plus grands d'applications, qu'il s'agisse de startups, de grandes entreprises ou d'agences gouvernementales.

+<b>UPSERT</b>
+</p><p>
+UPSERT, raccourci de « INSERT, ON CONFLICT UPDATE », est une fonctionnalité réclamée depuis longtemps par les développeurs d'applications.
+Elle permet de traiter de la même façon l'ajout ou l'actualisation de lignes.
+UPSERT simplifie le développement des applications web et mobile en permettant de laisser la base gérer les conflits entre modifications concurrentes des données.
+Cette fonctionnalité supprime également la dernière barrière à la migration d'applications MySQL historiques vers PostgreSQL.
+</p><p>
+Développée sur les deux dernières années par Peter Geoghegan, programmeur au sein de la société Heroku, l'implantation de UPSERT au sein de PostgreSQL est nettement plus souple et puissante que celle de la plupart des autres SGBDR.
+La nouvelle clause ON CONFLICT permet d'ignorer la nouvelle donnée, ou d'actualiser différentes colonnes ou relations, de façon à supporter les chaînes d'ETL (Extract, Transform, LOAD) les plus complexes.
+Et, à l'instar de PostgreSQL, cette fonctionnalité a été conçue pour être totalement concurrentielle, et s'intégrer avec les autres fonctionnalités de PostgreSQL, dont la réplication logique.

+PostgreSQL continue d'étendre les possibilités de sécurisation des accès, avec la nouvelle fonctionnalité Row Level Security (RLS).
+RLS propose un vrai contrôle d'accès par ligne et par colonne, qui s'intègre avec les outils externe de sécurisation, tel SELinux.
+PostgreSQL est déjà connu comme « la base la plus sécurisée par défaut ». RLS conforte cette position de meilleur choix par défaut pour les applications à fort besoin de sécurisation, telles que la conformité PCI, la dIrective Européenne de protection des données, et les standards de protection des données des systèmes de santé.
+</p><p>
+RLS est l'aboutissement de 5 ans d'ajout de fonctionnalités de sécurité à PostgreSQL, ce qui inclut les travaux de KaiGai Kohei de NEC, Stephen Frost de Crunchy Data, et ceux de Dean Rasheed. À travers cette fonctionnalité, les administrateurs de base de données peuvent définir des politiques de sécurité, qui filtrent les lignes visibles en fonction des utilisateurs.
+La sécurisation mises en place par ce biais est résistante aux injections SQL et autres trous de sécurité de niveau applicatif.

+<b>
+Fonctionnalités Big Data
+</b>
+</p><p>
+PostgreSQL 9.5 inclut de nombreuses nouvelles fonctionnalités pour les bases plus volumineuses, et l'intégration avec les systèmes Big Data.
+Ces fonctionnalités garantissent que PostgreSQL va continuer de jouer un rôle majeur dans le marché grandissant du Big Data en logiciels libres.
+Citons :
+</p><p>
+<b>Les index BRIN</b> : Ce nouveau type d'index permet la création d'index beaucoup plus petits, mais très efficaces, pour les tables volumineuses. Il est nécessaire que les données soient ordonnées.
+Par exemple, des tables contenant des millions de lignes de traces peuvent être indexées et interrogées en 5% du temps nécessaire lors de l'utilisation d'index de type BTree.
+</p><p>
+<b>Tris plus rapides</b> : PostgreSQL trie désormais les données textuelles et numériques plus rapidement, à l'aide d'un algorithme appelé "clés abrégées" ou "abbreviated keys".
+Cela accélère certaines requêtes qui nécessitent de trier des volumes considérables de données d'un facteur 2 à 12, et peut également accélérer la création d'index d'un facteur 20.
+</p><p>
+<b>CUBE, ROLLUP et GROUPING SETS</b> : Ces nouvelles clauses du standard permettent de produire des rapports avec plusieurs niveaux de synthèse en une seule requête.
+CUBE permet également une meilleure intégration de PostrgreSQL avec un nombre plus grand d'outils de création de rapports OLAP (Online Analytic Processing), tel Tableau.
+</p><p>
+<b>Les Foreign Data Wrappers (FDW)</b> : Ils permettent déjà d'utiliser PostgreSQL pour interroger des systèmes Big Data, tel Hadoop ou Cassandra. La version 9.5 ajoute IMPORT FOREIGN SCHEMA et les jointures au niveau des sources externes, ce qui rend les connexions aux données externes plus efficaces et plus faciles à établir.
+</p><p>
+<b>TABLESAMPLE</b>: Cette clause SQL permet de récupérer rapidement un échantillon statistique d'une table sans tri coûteux.
+</p><p>
+« Le nouvel index BRIN apparu dans PostgreSQL 9.5 est une fonctionnalité puissante qui permet à PostgreSQL de gérer et indexer des volumes de données difficiles, voire impossibles à traiter par le passé. Il permet de faire évoluer les données et les performances au delà de la limite considérée précédemment avec les bases relationnelles traditionnelles et fait de PostgreSQL une solution parfaite pour les analyses Big Data," déclare Boyan Botev, Lead Database Administrator, Premier, Inc.
