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}.
