pg_dump includes code in the dump that is supposed to update references
to match the new large object OIDs.  Check into why that didn't work
for you.  (One fairly likely possibility is that you stored the
references in the wrong type of column --- it has to be type "oid" or
"lo" or pg_dump won't think it needs updating.)
