there's no such thing as PostgreSQL 9.12, there's 9.1 of which the
current build is 9.1.9, and there's 9.2 which is currently 9.2.4.
You can build a active/standby failover cluster with PostgreSQL, but you
will need external cluster management software to manage the automatic
failover. You can use the built in streaming replication available in
9.0 and later to keep the standby server updated, or you can use
traditional shared storage managed by your cluster software.
btw, this is NOT a 'bug report' and does NOT belong on the pgsql-bugs
mail list, you should subscribe to the pgsql-general list for further
discussions.
