Which version of pg_dump did you use to dump the old database? The
recommended procedure is to use the newer version of pg_dump (ie:
pg_dump from 8.1.1) to dump the old database. It's possible that the
newer version of pg_dump has facilities in place to deal with this.
Those facilities would obviously be missing from older versions.
