I am stuck with redhat as the OS so I'll only have initdb. But this is a
good point. I assume there is nothing wrong with having multiple
postgres instances (clusters) all running under a single postgres user
on different ports on the same machine?
But then what is the best way to handle connecting to an individual
cluster (local only for admin purposes) with psql? Doesn't look like I
could go by the cluster name alone, but would have to manage (memorize)
connections by port number?
Thanks,
Sam
