Is possible to create a shared-storage postgresql server cluster?

0

PostgreSQL does not support clustering using shared storage on a SAN, SCSI backplane, iSCSI volume, or other shared media. Such “RAC-style” clustering isn’t supported. Only replication-based clustering is currently supported. See Replication, Clustering, and Connection Pooling information for details. Shared-storage ‘failover’ is possible, but it is not safe to have more than one postmaster running and accessing the data store at the same time. Heartbeat and STONITH or some other hard-disconnect option are recommended.
