+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>
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>

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 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>
