PostgreSQL {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}. {(http://postgresql.org/)}. (1999-09-18)
