Are you sure you need to? Methinks the lazy approach of letting them
auto-adjust on next UPDATE should work as well for OIDs as for user
There might be a few places that look at the pg_class.relhasoids
field where they should be examining the tuple header has-oid bit,
but I don't think there are many.
