PostgreSQL 9.0 Arrives
PostgreSQL 9.0 is out now.
PostgreSQL is an open source Object-Relational DBMS. With the 9.0 release, PostgreSQL adds built-in replication based on log shipping, and a mass permission-changing facility. Large objects now support permissions management as well, and support for anonymous code blocks has been added. There are new trigger features, such as SQL-standard-compliant per-column triggers and conditional trigger execution, and security updates including RADIUS authentication and a new contrib module for testing password strength.
