Dan,
Sure, just bring it up in a different directory and have it listen on a
different port. You could either dump/restore to get the data over to it or
use a replication tool such as slony or mammoth to do the deed. The latter
method has the benefit of keeping it up to date while you poke around if you
have a database which gets written to during your switchover time.
