Well, I agree, but I think making behavior changes after rc1 is a
non-starter. It's better to live with the incompatibility than to
change the behavior so close to release. At least, that's my
position. Getting the release out on time with a minimal bug count is
more important to me than a minor incompatibility in the meaning of
one GUC.
