PostgreSQL 9.0 Release Candidate Hits the Street
The first release candidate for PostgreSQL 9.0 is out, bringing a host of new features, including binary replication.The first release candidate for PostgreSQL 9.0 has arrived with built-in binary replication technology. Expected to be ready for final release sometime in September, the RC represents a significant overhaul for the database, said PostgreSQL core team member Josh Berkus. New features include per-column and conditional triggers, performance enhancements for object-relational-mapper queries and exclusion constraints. At the top of the list is binary replication.
"Binary replication is, of course, big news for the many people who are now looking for migration options due to the recent database company acquisitions," Berkus said. "While PostgreSQL had replication options before-such as Slony-I, Londiste, pgPool2 and Bucardo-the lack of any form of replication built into the PostgreSQL core and capable of very simple configurations has been a longstanding complaint of users seeking to migrate from MySQL, Sybase, Oracle and others."
