Were the issues that I mentioned regarding GIST (and maybe other AMs)
in the last paragraph of
http://postgr.es/m/CA+TgmoZEZ5RONS49C7mEpjhjndqMQtVrz_LCQUkpRWdmRevDnQ@mail.gmail.com

problem to me, and I don't see that there's been any discussion of it.
Those are correctness concerns separate from any wal_level tracking we
might want to do to avoid accidental mistakes.
