how large is the full database cluster?
if its only a few GB or whatever, and not grossly complex, pg_dumpall -h
oldhost | psql -h newhost, is the simplest way to move a complete set of
databases from an old server to a new. if there are large tables with
millions of rows indexed, make sure you set maintenance_work_mem on the
new server to 2GB before running this.
