That's good so far.

The other thing that is eating OID's are temporary objects. I personally
consider the implementation of temp tables broken for precisely that
matter. If your application uses temp tables, sooner or later it will
cause an OID counter wrap around and then you run the risk of random
transaction failures due to duplicate key errors on CREATE TEMP TABLE.
