I generally like to keep the Bucardo database on the same server as one
of the hosts, as one of the Bucardo->database connections is thus local
and super-fast, at the cost of a little more "all your eggs in one
basket". Keeping a copy of the bucardo schema elsewhere helps reduce
that risk, as everything needed to bring Bucardo up again elsewhere is
in the (small) bucardo database. It's also nice to be able to toggle
back and forth via psql from the bucardo database to the real one, but
that's certainly not a reason to base a decision like this on. :)
 In theory, you could replicate /that/ database as well, but it
changes infrequently enough on my end that I've never tried it.
