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.
