release of PostgreSQL 9.4, the latest version of the world's leading open source database, is available today. This beta contains previews of all of the features which will be available in version 9.4, and is ready for testing by the worldwide PostgreSQL community. Please download, test, and report what you find. Major Features -------------- The new major features available for testing in this beta include: * JSONB: 9.4 includes the new JSONB "binary JSON" type. This new storage format for document data is higher-performance, and comes with indexing, functions and operators for manipulating JSON data. * Replication: The new Data Change Streaming API allows decoding and transformation of the replication stream. This lays the foundation for new replication tools that support high-speed and more flexible replication and scale-out solutions. * Materialized Views with "Refresh Concurrently", which permit fast-response background summary reports for complex data. * ALTER SYSTEM SET, which enables modifications to postgresql.conf from the SQL command line and from remote clients, easing administration tasks.

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.
