How many OIDs have been recovered? If the answer is "none" (i.e. the
database doesn't have many deletes), then there isn't likely much you
can do about it -- reloading the database is going to cause the same
problem.

As Chris says in another message, you can use Slony to replicate the
database, in order not to have a long outage. Note, too, that since
you say most tables don't actually use this pg_oid_status method, you
can get away with creating most of the tables without OIDs, which
will stave off your problem for a while. That'd probably even help
if the database mostly just grows, depending (of course) on where the
growth is.
