pg_dumpall doesn't do the right thing for you?
Copy the entire directory, and then issue the commands "DROP DATABASE
blah" which you don't want on the new machine?

Use Slony (http://slony.info) to get live replication/load balancing
instead.

Or pgcluster (don't have a link offhand) to allow multi-master load
balancing.
