A little experimentation suggests that we might be able to add a function
uuid_generate_v3(uuid, bytea) alongside the uuid_generate_v3(uuid, text)
one without creating serious problems --- in ambiguous situations, it
seems the text one would be preferred, so we'd not break existing queries.

I have no interest in preparing such a patch myself, though.
