PGCluster is a multi-master and synchronous replication tool of PostgreSQL based on shared-nothing architecture, developed by Atsushi Mitani and PGCluster developer’s team.
The lead developer of pgCluster has moved on to pgCluster2, and all development on pgCluster has halted. While pgCluster’s code is not fully mature, it is being used in production at a few sites.
A complete pgcluster requires at least 6 machines (3 database servers, 2 load balancers and a monitoring/failover controller). Also, it requires modifications to PostgreSQL core, so the Postgres version of pgCluster is always behind the mainstream version.
