PostgreSQL

    /'post-gres-kyu-el/ An enhancement of the
   POSTGRES database system.

   PostgreSQL is an advanced relational database management
   system with some object oriented approaches.  PostgreSQL is
   developed and distributed as free software, and while
   retaining its freedom it remains technically and featurewise a
   worthy competitor to even the most advanced commercial
   alternatives.

   It was also one of the first databases to offer MVCC as
   opposed to row-level locking or table locking, thereby
   greatly improving multi-user performance.

   PostgreSQL implements an extended subset of ANSI SQL and
   runs on many platforms.  It also has interfaces to many
   different programming languages and database protocols,
   like ODBC and JDBC.
