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.
