Looks sane in a quick once-over, except for the documentation entry.
I'm not really thrilled with "text, text or bytea, bytea" because it
seems easy to misparse. Moreover, as written the entry claims that
the return type is text either way, which is wrong. You could fix
the latter by writing "same as argument data type", but I wonder
whether it'd be better to make separate table entries for the two
forms.
