That is a completely unacceptable kluge.  Quite aside from being ugly as
sin, it probably breaks more things than it fixes, first because it breaks
the fundamental semantics of equal() across the board, and second because
it puts catalog lookups into equal(), which *will* cause problems.  You
can not expect that this will get committed, not even as a "temporary fix".
