I've got 3 different database servers (db01, db02 and db03).
I would like to have a WAL standby server that replays logs for all 3 in
case one goes down, so I can promote that particular server.
Can I do this by installing 3 separate postmasters on this machine?
Obviously, if 2 went down at the same time, I'd have to do some magic to
bring up another machine, but I'm not sure that's a concern.
It'll be a RedHat RHEL-4 box on pg 8.1x
