Is there any tutorials or detailed instructions on how to set up HA postgresql
& failover? The documentation
(http://www.postgresql.org/docs/9.0/interactive/warm-standby-failover.html) on
this topics is pretty scarce.
The scenario I'm most interested in is this:
2 servers - a master and a hot standby. All writes are sent to master, reads
are split between master and hot standby.
1) If the hot standby goes down, how do I redirect reads to the master?
2) If the master fails
-how do I automatically promote the standby to master and send all
reads/writes to the new master?
-what happens when the old master comes back up? Do I need to so anything
to make it catches up to the new master?
Thanks.
