I think these messages are sufficiently confusing that we could call
it a bug fix to improve them. As long as we don't change the SQLSTATE
that's thrown, it's hard to claim that there's any real application
compatibility hazard from changing them.
I just don't want to call this point a release blocker. It's not
about changing any semantics or the set of things that work.
