Well, put a unique index on the contents column. Better to fail an
insert than to get a conflict of LO OIDs.
If you were on 7.4 or later you could do ALTER TABLE SET WITHOUT OIDS so
you'd not be sucking up OIDs for the table rows themselves. On 7.3 the
only way would be to drop and recreate the larger tables WITHOUT OIDS,
which is probably going to be painful :-(.
