+<b>12 ΣεπτεμβÏ?ίου 2011:</b>
+Η Ομάδα Ανάπτυξης PostgreSQL (PostgreSQL Global Development Group) ανακοινÏ?νει την έκδοση 9.1.
+Αυτή η έκδοση της Ï€Ï?ωτοπόÏ?ου ανοιχτοÏ? κÏ?δικα σχεσιακής
+βάσης δεδομένων Ï€Ï?οσφέÏ?ει Ï€Ï?ωτοποÏ?ιακή τεχνολογία, ασÏ?γκÏ?ιτη επεκτασιμότητα και νέα χαÏ?ακτηÏ?ιστικά,
+ όπως σÏ?γχÏ?ονο replication, K-Nearest Neighbor indexing, και wrappers για εξωτεÏ?ικές πηγές δεδομένων.
+</p><p>
+<i>
+«Η PostgreSQL 9.1 Ï€Ï?οσφέÏ?ει μεÏ?ικές από τις πιο Ï€Ï?οηγμένες δυνατότητες για επιχειÏ?ησιακό λογισμικό συγκÏ?ιτικά με οποιαδήποτε
+βάση δεδομένων ανοικτοÏ? κÏ?δικα και υποστηÏ?ίζεται από μια δυναμική και καινοτόμο κοινότητα με αποδεδειγμένη επιτυχία στη βάση των πελατÏ?ν.
+Η PostgreSQL κατέχει καλή θέση και όσο αφοÏ?ά τη δημιουÏ?γία και εκτέλεση εφαÏ?μογÏ?ν στο cloud», δήλωσε ο ΑντιπÏ?όεδÏ?ος R&D της Vmware Charles Fan.
+</p><p>
+
+<h3>ΑπαντÏ?ντας σε ΧÏ?ήστες</h3>
+<p>
+Η Έκδοση 9.1 διαθέτει αÏ?κετά χαÏ?ακτηÏ?ιστικά τα οποία οι χÏ?ήστες έχουν ζητήσει τα Ï€Ï?οηγοÏ?μενα χÏ?όνια,
+αίÏ?οντας φÏ?αγμοÏ?Ï‚ στην ανάπτυξη ή μεταφοÏ?ά εφαÏ?μογÏ?ν σε PostgreSQL.
+Στα χαÏ?ακτηÏ?ιστικά πεÏ?ιλαμβάνονται:
+</p><ul>
+<li><b>ΣÏ?γχÏ?ονο Replication</b>:
+ΕπιτÏ?έπει υψηλή διαθεσιμότητα (high-availability) με ταυτόχÏ?ονη εγγÏ?ηση ακεÏ?αιότητας δεδομένων πάνω από πολλαπλοÏ?Ï‚ κόμβους</li>
+<li><b>Per-Column Collations</b>: ΥποστήÏ?ιξη για γλωσσικά-σωστή ταξινόμηση ανά βάση δεδομένων, πίνακα ή στήλη.</li>
+<li><b>Unlogged Tables</b>: ΒελτιÏ?νει σε μεγάλο βαθμό την απόδοση χÏ?ησης Ï€Ï?οσωÏ?ινων δεδομένων.</li>
+</ul><p>
+«Η Heroku Ï„Ï?έχει τη μεγαλÏ?τεÏ?η εγκατάσταση PostgreSQL ως υπηÏ?εσία στον κόσμο» είπε ο James Lindenbaum, συνιδÏ?υτής της Heroku.
+«Η δυνατοτητα συγχÏ?ονου data replication της 9.1 παÏ?έχει στους πελάτες μας νέους καινοτόμους Ï„Ï?όπους για την Ï€Ï?οστασία κÏ?ίσιμων δεδομένων
+και πιστοποιεί ότι η PostgreSQL είναι μία από της ταχÏ?τεÏ?α εξελισσόμενες βάσεις δεδομένων»
+</p>
+
+
+<h3>Advancing the State of the Art</h3>
+<p>
+Η κοινότητα των contributors καινοτομεί με Ï€Ï?ωτοποÏ?ιακές λειτουÏ?γίες. Η Έκδοση 9.1
+πεÏ?ιλαμβάνει πολλά χαÏ?ακτηÏ?ιστικά τα οποία είναι νέα γενικά για όλη την βιομηχανία βάσεων δεδομένων, όπως:
+</p><ul>
+<li><b>K-Nearest-Neighbor Indexing</b>: index στην «αποσταση» για ταχιτεÏ?ο εντοπισμο και εÏ?ωτηματα αναζήτησης κειμενου.</li>
+<li><b>Serializable Snapshot Isolation </b>: ΔιατηÏ?εί ταυτόχÏ?ονα transactions χωÏ?ίς κλείδωμα, με χÏ?ήση της τεχνικης «true serializability»</li>
+<li><b>Writeable Common Table Expressions </b>: Εκτέλεση πολÏ?πλοκων και σε πολλαπλά στάδια εÏ?ωτηματων αλαγης δεδομενων σε ενα εÏ?ωτημα (With clause) </li>
+<li><b>Ενισχυση ασφάλειας </b>: ανάπτυξη στÏ?ατιωτικÏ?ν Ï€Ï?οδιαγÏ?αφÏ?ν ασφάλειας και ΥποχÏ?εωτικός Έλεγχος Î Ï?όσβασης </li>
+</ul><p>
+«Η OpenERP πάντα βασίζονταν στα επιχειÏ?ησιακής κλάσης χαÏ?ακτηÏ?ιστικά της PostgreSQL Ï?στε να παÏ?έχει μία γÏ?ήγοÏ?η, αξιόπιστη και επεκτάσιμη βάση για τις ΕπιχειÏ?ησιακές
+ΕφαÏ?μογές οι οποίες υποστηÏ?ίζουν τις διαδικασίες των πελατÏ?ν μας σε καθημεÏ?ινή βάση. Η ακεÏ?αιότητα των δεδομένων σε υψηλά concurrent και transactional
+ πλαίσια είναι ένα κÏ?ίσιμο θέμα για εμάς, και είμαστε πολÏ? ενθουσιασμένοι σχετικά με τη νέα δυνατότητα Serializable Snapshot Isolation της PosgtreSQL 9.1!»
+δήλωσε ο Olivier Dony, Community Manager της OpenERP.
+
+
+</p>
+<h3>Επεκτινοντας την Database Engine</h3>
+<p>
+
+Η δυνατότητα για Επεκτασιμότητα της PostgreSQL επιτÏ?έπει στους χÏ?ήστες να Ï€Ï?οσθέτουν νέες λειτουÏ?γίες σε βάσεις δεδομένων παÏ?αγωγής, και να τις χÏ?ησιμοποιοÏ?ν για εÏ?γασίες που
+άλλα συστήματα βάσεων δεδομένων δεν μποÏ?οÏ?ν να ανταπεξέλθουν. Η Έκδοση 9.1 Ï€Ï?οσθέτει νέα εÏ?γαλεία επεκτασιμότητας, συμπεÏ?ιλαμβανομένων:
+</p><ul>
+<li><b>Foreign Data Wrappers</b>: σÏ?νδεση και εÏ?ωτήματα σε άλλες βάσεις δεδομένων από την PostgreSQL</li>
+<li><b>Extensions</b>: ευκολία στην φόÏ?τωση, και διαχείÏ?ιση νέων λειτουÏ?γιÏ?ν της PostgreSQL</li>
+</ul>
+Όλα τα παÏ?απάνω χαÏ?ακτηÏ?ιστικά, και πολλά άλλα, είναι καταγεγÏ?αμμένα λεπτομεÏ?Ï?Ï‚ στο

+ αίÏ?οντας φÏ?αγμοÏ?Ï‚ στην ανάπτυξη ή μεταφοÏ?ά εφαÏ?μογÏ?ν σε PostgreSQL. ΜεταξÏ? αυτÏ?ν πεÏ?ιλαμβάνονται:
+ </p><dl>
+ <dt><b>ΣÏ?γχÏ?ονο Replication for Clustering:</b></dt><dd>
+ΕπιτÏ?έπει υψηλή διαθεσιμότητα (high-availability) με ταυτόχÏ?ονη εγγÏ?ηση ακεÏ?αιότητας δεδομένων πάνω από πολλαπλοÏ?Ï‚ κόμβους
+με την εγκατάσταση PostgreSQL clusters κάνοντας χÏ?ήση σÏ?γχÏ?ονου replication. Το σÏ?γχÏ?ονο replication υποστηÏ?ίζει την δυνατότητα "2-safe replication",
+ή οποία διασφαλίζει ότι τα transactions έχουν επιβεβαιωθεί από έναν standby
+ server σε συνδυασμό με τον master, μειÏ?νοντας σημαντικότατα την πιθανότητα απÏ?λειας δεδομένων. Μόνο η PostgreSQL έχει transaction-level synchronous replication,
+ επιτÏ?έποντας στους χÏ?ήστες να διαλέξουν ανά transaction μεταξÏ? χÏ?όνου απόκÏ?ισης και ασφάλειας των δεδομένων.</dd>
+ <dt><b>Per-column Collations για πολυ-γλωσσικές βάσεις δεδομένων:</b></dt><dd> Οι χÏ?ήστες μποÏ?οÏ?ν Ï„Ï?Ï?α να θέτους το collation για strings σε επίπεδο στήλης.
+Αυτό επιτÏ?έπει Ï€Ï?αγματικά πολυ-γλωσσικές βάσεις δεδομένων, όπου κάθε στήλη είναι σε διαφοÏ?ετική γλÏ?σσα,
+και το indexing και η ταξινόμηση επιτελοÏ?νται οÏ?θά για αυτήν τη γλÏ?σσα.</dd>
+ <dt><b>Unlogged Πίνακες για τη Βελτίωση της Απόδοσης:</b></dt><dd> Όταν η απόδοση είναι πιο σημαντική από την ανθεκτικότητα (durability),
+ οι unlogged πίνακες Ï€Ï?οσφέÏ?ουν έναν Ï„Ï?όπο για την βελτίωση της απόδοσης, οσο η διαχείÏ?ιση γίνεται μέσα στην PostgreSQL.
+ Η απομάκÏ?υνση του logging μειωνει το I/O overhead, επιτÏ?έποντας βελτιÏ?σεις στην απόδοση έως και 10 φοÏ?ές συγκÏ?ινόμενο με logged πίνακες.
+ Τα σενάÏ?ια στα οποία αναμένεται η χÏ?ήση των unlogged πινάκων πεÏ?ιλαμβάνουν web session data, real time logging, ETL και temporary/intermediate πίνάκες για χÏ?ήση απο procedural functions.</dd>

+ Η κοινότητά μας είναι καινοτόμα, παÏ?αδίδοντας Ï€Ï?ωοτποÏ?ιακά χαÏ?ακτηÏ?ιστικά τα οποία είναι νέα στην βιομηχανία των βάσεων δεδομένων.
+Κάποια από αυτά τα χαÏ?ακτηÏ?ιστικά είναι διαθέσιμα μόνο στην PostgreSQL.

+ Ï€Ï?οσφέÏ?ουν καινοτομικο indexing Ï€Ï?ος αποφυγή ακÏ?ιβÏ?ν table scans. Το KNN εμπλουτίζει τις δυνατότητες query της PostgreSQL με το να χÏ?ησιμοποιεί την μαθηματική "απόσταση"
+ για indexing και αναζητήσεις. Αυτοί οι δείκτες μποÏ?οÏ?ν να χÏ?ησιμοποιηθοÏ?ν για να εμπλουτίσουν συνήθεις αναζητήσεις κειμένου, αναζητήσεις text-similarity, geospatial location comparisons
+ και άλλα εÏ?ωτήματα. Δοκιμαστικές αναζητήσεις που έκαναν 2 δευτεÏ?όλεπτα χωÏ?ίς το ΚÎ?Î? index επέστÏ?εψαν σε 20 ms με αυτό το χαÏ?ακτηÏ?ιστικό. Οι text search δείκτες μποÏ?οÏ?ν Ï„Ï?Ï?α να διαμοÏ?φωθοÏ?ν
+ Ï?στε να Ï€Ï?οσφέÏ?ουν υποστήÏ?ιξη indexing για LIKE '%string%' εÏ?ωτήματα χωÏ?ίς να αλλάξει το SQL. Η PostgreSQL είναι μεταξÏ? των Ï€Ï?Ï?των συστημάτων βάσεων δεδομένων που έχουν KNN.</dd>
+ <dt><b>Serializable Snapshot Isolation:</b></dt><dd> ΕπιτÏ?έπει στους χÏ?ήστες να επιβάλλουν αυθαιÏ?έτως πολÏ?πλοκους user-defined business rules μέσα στη βάση δεδομένων χωÏ?ίς μπλοκάÏ?ισμα (*blocking*),
+ με το να διαγνÏ?σκει αυτόματα live race conditions στα SQL transactions σε runtime. Αυτό το χαÏ?ακτηÏ?ιστικό, Ï€Ï?ος το παÏ?όν, υπάÏ?χει μόνο στην PostgreSQL.</dd>

+ <h3>Επεκτείνοντας την Database Engine</h3>
+ <p> Η επεκτασιμοτητα της PostgreSQL επιτÏ?έπει στους χÏ?ήστες να Ï€Ï?οσθέτουν νέα λειτουÏ?γικότητα σε μία βάση δεδομένων παÏ?αγωγής ενω Ï„Ï?έχει,
+ και να χÏ?ησιμοποιήσουν αυτή τη λειτουÏ?γικότητα για δουλειές που κανένα άλλο σÏ?στημα βάσεων δεδομένων δεν μποÏ?εί να εκτελέσει.
+ Η έκδοση 9.1 ποÏ?σθέτει νέα κÏ?ίσιμα χαÏ?ακτηÏ?ιστικά σχετικά με την επεκτασιμότητα, που πεÏ?ιλαμβάνουν:

+ Τα FDWs κάνουν την PostgreSQL ένα δυναμικό εÏ?γαλείο για την ενοποίηση enterprise δεδομένων, και κάνουν το migration ευκολότεÏ?ο.
+ Τα FDWs που είναι αÏ?χικÏ?Ï‚ διαθέσιμα από την κοινότητα πεÏ?ιλαμβάνουν comma-separated-value (CSV) αÏ?χεία, Oracle, MySQL, CouchDB, ακόμα και Twitter πηγές.

+ Στα 25 χÏ?όνια που μεσολάβησαν, η POSTGRES έγινε ένα έÏ?γο ανοικτοÏ? κÏ?δικα, μετατÏ?άπηκε Ï?στε να χÏ?ησιμοποιεί την SQL,
+ άλλαξε το όνομά της σε PostgreSQL, και έγινε μία από τις κοÏ?υφαίες σχεσιακές βάσεις δεδομένων.

+<h3>Îndeplinirea cerinţelor venite de la utilizatori</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:
+Versiunea 9.1 introduce o serie facilităţi cerute de mult timp de către utilizatori, îndepărtînd astfel unele obstacole care stăteau în calea implementării anumitor aplicaţii noi sau portării lor la PostgreSQL. Noile facilităţi sînt:
</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>
+<dt><b>Replicare Sincronă:</b></dt><dd> Permite obţinearea unui grad înalt de disponibilitate prin instalarea de clustere PostgreSQL sincronizate între ele în mod sincron. Replicarea sincronă suportă aşa numita "2-safe replication" care garantează că tranzacţiile sînt confirmate de către serverul standby, ceea ce limitează riscul unor eventuale pierderi de date. PostgreSQL este singurul care oferă replicare sincronă la nivel de tranzacţie, ceea ce permite utilizatorilor să aleagă pentru fiecare tranzacţie în parte între viteza de răspuns şi siguranţa datelor.</dd>
+<dt><b>Collations la nivel de coloană:</b></dt><dd> Utilizatorii pot acum preciza collation-ul pentru fiecare coloană în parte. Aceasta permite bazei de date să suporte cu adevărat mai multe limbi simultan, adică este posibil ca fiecare coloană text să aibă setată o altă limbă - iar indecşii şi sortările să fie efectuate corect conform fiecărei limbi.</dd>
+<dt><b>Tabele ne-logate:</b></dt><dd> Atunci cînd viteza este mai importantă decît siguranţa datelor, tablele ne-logate oferă posibilitatea de a mari performanţele păstrînd datele în PostgreSQL. Renunţarea la logare reduce volumul I/O , obţinîndu-se timpi de răspuns cu pînă la 10 ori mai mici. Tabelele ne-logate pot fi folosite de exemplu pentru a memora date efemere cum sînt cele corespunzătoare sesiunilor web, mesaje de log în timp real, ETL sau tabele ce conţin date temporare.</dd>
</dl>
-<h3>Advancing the State of the Art</h3>
+<h3>Inovaţii</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.
+Comunitatea noastră a introdus inovaţii de ultimă oră. O parte dintre facilităţile prezentate mai jos sînt disponibile numai în 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>
+<dt><b>K-Nearest-Neighbor (KNN) Indexing:</b></dt><dd> Noua metodă de indexare KNN-GiST permite parcurgerea costisitoare a taelelor. KNN extinde capabilităţile PostgreSQL prin utilizarea "distanţei matematice" pentru indexare şi căutări. Aceşti indecşi pot fi folosiţi pentru căutări text, căutări după similaritatea valorilor text, comparaţii geospaţiale şi nu numai. De exemplu există cazuri în care o cerere care înainte dura 2 secunde se execută acum in 20 milisecunde. Indecşii definiţi pe coloane text pot fi configuraţi să fie utilizabili şi pentru cererile de tip LIKE '%string%' , fără nici un fel de modificări ale cererilor SQL. PostgreSQL este printre primele sisteme de baze de date care au KNN.</dd>
+<dt><b>Serializable Snapshot Isolation:</b></dt><dd> Le permite utilizatorilor să implementeze reguli business complexe arbitrare fără a necesia blocking , datorită detecţiei automate a conflictelor dintre tranzacţiile SQL. La momentul actual, numai PostgreSQL are această funcţionalitate.</dd>
+<dt><b>Writeable Common Table Expressions (wCTE):</b></dt><dd> Suportă integritatea relaţională a daelor prin faptul că permie execuţia update-urilor complexe (în cascadă) într-o singură comoandă. Prin utilizarea rezultatelor unui query la execuţia unui alt query devine posibil update-ul recursiv, ierarhic de-a lungul înregistrarilor legate prin chei externe. PostgreSQL are cea mai completă şi flexibilă implementare a acestei funcţionalităţi.</dd>
+<dt><b>Security-Enhanced Postgres (SE-Postgres):</b></dt><dd> Permite implementarea unei securităţi de nivel militar, precum şi mandatory access control, datorită integrarii complete a Security-Enhanced Linux (SE-Linux). SE-Linux este un proiect NSA care adaugă kernelului Linux o serie de funcţii pentru securitate. SE-Linux este inclus în majoritatea distribuţiilor Linux , cum sînt Red Hat, CentOS, Debian, Ubuntu şi nu numai. PostgreSQL este singurul sistem de baze de date care are această integrare strînsă cu SE-Linux.</dd>

</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>
+<dt><b>Foreign Data Wrappers (FDW):</b></dt><dd> Ca parte integrantă a suportului pentru standardul SQL/MEDA, facilitatea FDW permit efectuarea de cereri către seturi de date externe, care nu sînt stocate în baza de date PostgreSQL. FDW le permite utilizatorilor să creeze "drivere" pentru ataşarea la surse externe de date, care apoi pot fi folosite ca tabele read-only. FDW fac din PostgreSQL o unealtă puternică pentru integrarea datelor, iar în plus pot uşura procesul de migrare. FDW-urile disponibile iniţial includ : fişiere CSV, Oracle, MySQL, CouchDB, şi chiar surse Twitter. Este de aşteptat ca în curînd să fie realizate mult mai multe.</dd>
+<dt><b>Extensions:</b></dt><dd> PostgreSQL a fost dintotdeauna extensibil. Noutatea constă în faptul că acum a fost introdus conceptul de EXTENSION , ca obiect al bazei de date. Acesta permite utilizatorilor să creeze, încarce, actualizeze şi să gestioneze multitudinea de extensii disponibile. Noul site PGXN.org oferă un repository pentru extensii, de unde utilizatorii pot descărca extensii sau pot pune la dispoziţia altora extensiile realizate de ei. </dd>

-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.
+Proiectul POSTGRES a început la University of California, Berkeley, în iunie 1986 odată cu publicarea design-ului original POSTGRES de către Lawrence A. Rowe şi Michael R. Stonebraker.

+<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
