True. But you might want to separate them if it will make it more
flexible for you (being able to dump all of the smaller database and
move it to a different machine, etc.) But if you separate them, it will
be harder to do cross-database queries (but see dblink/ in contrib for a
solution). All things being equal, I'd probably keep them together.
