I think that's not proving what you thought; the case is correctly handled
if you quote:

regression=# create table "123"(z int);
CREATE TABLE
regression=# select '123'::regclass;regclass 
----------123
(1 row)

regression=# select '"123"'::regclass;regclass 
----------"123"
(1 row)

But I agree that we don't want these functions accepting numeric OIDs,
even though ::regclass must.
