It'd be nontrivial, primarily because of portability issues: not all
platforms even have 64-bit ints, much less 64-bit ints that are fast
enough to justify making a core datatype be 64 bits. (Not only OID,
but also Datum, would have to become 64 bits. That is a *very*
pervasive change, and one with serious implications for performance.)
