Assuming there's only one or two databases in the cluster, it would be
pretty easy to just do a
dropdb -h dest dbname1
dropdb -h dest dbname2
createdb dbname1
createdb dbname2
pg_dump -h source dbname1|psql -h dest
pg_dump -h source dbname2|psql -h dest
That way there's no need to take down the source server or do anything
special to it.
