PostgreSQL is a powerful, open source object-relational database system. It has more than 15 years of active development and a proven architecture that has earned it a strong reputation for reliability, data integrity, and correctness. It runs on all major operating systems, including Linux, UNIX (AIX, BSD, HP-UX, SGI IRIX, Mac OS X, Solaris, Tru64), and Windows. It is fully ACID compliant, has full support for foreign keys, joins, views, triggers, and stored procedures (in multiple languages). It includes most SQL:2008 data types, including INTEGER, NUMERIC, BOOLEAN, CHAR, VARCHAR, DATE, INTERVAL, and TIMESTAMP. It also supports storage of binary large objects, including pictures, sounds, or video. It has native programming interfaces for C/C++, Java, .Net, Perl, Python, Ruby, Tcl, ODBC, among others.

What is new in version 9.2

This release has been largely focused on performance improvements, though new SQL features are not lacking. Work also continues in the area of replication support. Major enhancements include:

Allow queries to retrieve data only from indexes, avoiding heap access (index-only scans)

Allow the planner to generate custom plans for specific parameter values even when using prepared statements

Improve the planner's ability to use nested loops with inner index scans

Allow streaming replication slaves to forward data to other slaves (cascading replication)

Allow pg_basebackup to make base backups from standby servers

Add a pg_receivexlog tool to archive WAL file changes as they are written

Add the SP-GiST (Space-Partitioned GiST) index access method

Add support for range data types

Add a JSON data type

Add a security_barrier option for views

Allow libpq connection strings to have the format of a URI

Add a single-row processing mode to libpq for better handling of large result sets
