Sure, but I think we are still a few years away from being able to
assume that every platform of interest can support 8-byte OIDs (and
furthermore, won't see a significant performance degradation --- keep
in mind that widening Datum to 8 bytes is a change that affects all
datatypes not just Oid). There's also the Oids-are-in-the-wire-protocol
problem. In short, that's a long-term solution not a near-term one.

Nope. pg_description is the only offender.
