PostgreSQL is a robust, next-generation, Object-Relational DBMS (ORDBMS),
derived from the Berkeley Postgres database management system.  While
PostgreSQL retains the powerful object-relational data model, rich data types
and easy extensibility of Postgres, it replaces the PostQuel query language
with an extended subset of SQL.

PostgreSQL is free and the complete source is available.

This package contains the database documentation.
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: enable high-availability with consistency across multiple servers * Per-Column Collations: support linguistically-correct sorting per database, table or column. * Unlogged Tables: greatly improves performance for ephemeral data Our community of contributors innovates with cutting-edge features. Version 9.1 includes several which are new to the database industry, such as: * K-Nearest-Neighbor Indexing: index on "distance" for faster location and text search queries * Serializable Snapshot Isolation: keeps concurrent transactions consistent without blocking, using "true serializability" * 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 2011-09-15 10:27:38 +02:00			`PostgreSQL is a robust, next-generation, Object-Relational DBMS (ORDBMS),`
