Hmm ... I was thinking it didn't matter, but on closer look, the
int4->oid cast is implicit while the oid->int4 one is only assignment.
So you'd need to write a cast to pass an OID if we declare the functions
as taking int4.  But you'll need a cast anyway if you want to pass a
single OID to the int8-taking version (that's an assignment cast too).

The downside of declaring the functions to take OID is that people might
think they could *only* use OIDs, which isn't so, they can use any
int4-sized key they feel like.

Not seeing a strong reason one way or the other ... what do you think?

That's in the core code I think, so it won't change.
