Probably not; the parser would have no principled way to resolve pg_get_serial_sequence('foo', 'bar') as one or the other. I'm not sure offhand if it would throw error or just choose one, but if it just chooses one it'd likely be the text variant. It's possible that we could get away with just summarily changing the argument type from text to regclass. ISTR that we did exactly that with nextval() years ago, and didn't get too much push-back. But we couldn't do the same for the return type. Also, this approach does nothing for the concern about the name being misleading. regards, tom lane
