It's not fast, but it works. If your write load is under 30MB/sec it's definitely an option. I run DRBD over SSH tunnels to get around the random IP address issue. I use heartbeat on top for resource management/failover (I know it's not ideal with the single communications path, but what can you do), and DDNS with really short TTLs. I've also had success using the native replication to spin read-only slaves off those HA masters, using pgpool to load balance selects. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
