I have only seen this problem if the column that stores the reference
to the BLOB is *not* of type "oid".  If you store your BLOB references
in an "oid" column, pg_restore will "fix up" the references for you
when the BLOBs get renumbered.

This is kind of an annoying restriction as the automatic DB-creation
software I was using didn't support oid columns, but it does work.
