Why would that be a problem if each is configured to listen on different
addresses?
But maybe a better question to ask would be how people are doing failover
in the case where you have two servers, each handling a seperate set of
data and acting as backup for each other. I fully expect things to go
slower during failover periods, but in my case, that's better than
doubling my hardware.

I'm trying to impliment an automatic failover system, and am running into
the problem that when I try to start multiple postgres clusters on the

change the file it's looking for via an option? Nothing seemed obvious
from a quick review of the docs, short of (presumably) changing the port
number, which I don't want to do.
That lock file exists specifically to keep you from doing that (ie,
having more than one postmaster listening on the same port). Trying
to defeat the lock is not a good idea.
