PostgreSQL 11, the latest version of the world’s most advanced open source database. PostgreSQL 11 provides users with improvements to overall performance of the database system, with specific enhancements associated with very large databases and high computational workloads. Further, PostgreSQL 11 makes significant improvements to the table partitioning system, adds support for stored procedures capable of transaction management, improves query parallelism and adds parallelized data definition capabilities, and introduces just-in-time (JIT) compilation for accelerating the execution of expressions in queries. "For PostgreSQL 11, our development community focused on adding features that improve PostgreSQL's ability to manage very large databases," said Bruce Momjian, a core team member of the PostgreSQL Global Development Group. "On top of PostgreSQL's proven performance for transactional workloads, PostgreSQL 11 makes it even easier for developers to run big data applications at scale." PostgreSQL benefits from over 20 years of open source development and has become the preferred open source relational database for developers. The project continues to receive recognition across the industry, and has been featured as the "DBMS of the Year 2017" by DB-Engines and in the SD Times 2018 100. PostgreSQL 11 is the first major release since PostgreSQL 10 was released on October 5, 2017. The next update release for PostgreSQL 11 containing bug fixes will be PostgreSQL 11.1, and the next major release with new features will be PostgreSQL 12.

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.
