[Pgpool-general] uptime for maintenance

[Janos Erdelyi]

Is there a fairly standard way to do maintenance on a pgpool instance
while not interrupting service too much for end-users?
I was thinking of using heartbeat with a shared ip between two pgpool
instances so that i could fail one out, do machine updates, upgrade
the pgpool version, etc.

is this a fairly typical (and successful) route?
