Users (and groups) are global across each Postgres installation.
So what you'd need to do is something like this:

pg_dump the desired database, and do "pg_dumpall -g" to get a script
recreating all your users and groups.  Edit out the non-pertinent
part of that script.  Run the users/groups script and then the pg_dump
script on the target machine.
