PostgreSQL is a sophisticated Object-Relational DBMS, supporting almost all SQL constructs, including subselects, transactions, and user-defined types and functions. It is the most advanced open-source database available anywhere. Commercial Support is also available.

The original Postgres code was the effort of many graduate students, undergraduate students, and staff programmers working under the direction of Professor Michael Stonebraker at the University of California, Berkeley. In 1995, Andrew Yu and Jolly Chen took on the task of converting the DBMS query language to SQL and created a new database system which came to known as Postgres95. Many others contributed to the porting, testing, debugging and enhancement of the Postgres95 code. As the code improved, and 1995 faded into memory, PostgreSQL was born.

PostgreSQL development is presently being performed by a team of Internet developers who are now responsible for all current and future development. The development team coordinator is Marc G. Fournier scrappy@PostgreSQL.ORG. Support is available from the PostgreSQL developer/user community through the support mailing list questions@PostgreSQL.ORG.

PostgreSQL is free and the complete source is available.
