We are proud to announce that our 100% free and open source Postgres High Availability Bundle (PostgresHA = PostgreSQL + pgHA) is now available as a Developers Sandbox for OSX and Linux 64.
This proven solution leverages PostgreSQL's native streaming replication technology and pgBouncer. It efficiently supports multiple read-only slaves, seamless DDL replication, and various failover and/or disaster recovery modes of operation.
