I didn't particularly like that either. The test is off-by-one, for
one thing (a type created right at OID wraparound could have
FirstNormalObjectId). However, it seems reasonable to avoid fruitless
syscache searches for builtin types, and I'm not seeing a lot of point
to wrapping this test in some macro.
