PostgreSQL is a powerful, open source object-relational database system that's been under active development for over 15 years.

An enterprise class database, PostgreSQL boasts sophisticated features such as Multi-Version Concurrency Control (MVCC), point in time recovery, tablespaces, asynchronous replication, nested transactions (savepoints), online/hot backups, a sophisticated query planner/optimizer, and write ahead logging for fault tolerance. It supports international character sets, multibyte character encodings, Unicode, and it is locale-aware for sorting, case-sensitivity, and formatting.

PostgreSQL has a SQL implementation that strongly conforms to the ANSI-SQL 92/99 standards. It has full support for subqueries (including subselects in the FROM clause), read-committed and serializable transaction isolation levels.

This JumpBox includes PostgreSQL 8 along with PHPPgAdmin setup and ready to run. The PostgreSQL server is network accessible and provides a great storage engine for a broad array of applications.
