I don't mind postponing the inheritance/GROUP-BY issue on that basis,
because it's an identifiable feature that doesn't work (and never has
worked).  I'm more troubled about the cache issue, because that could
give rise to hard-to-predict flaky behavior; we might waste a lot of
time chasing bug reports that ultimately reduce to that problem but
are not easily recognizable as such.

Bruce seemed to think that we could just flush the sys caches and
relation cache completely during xact abort.  This would probably be
less efficient than identifying the specific entries to get rid of, but
it would plug the hole in the dike well enough for 6.5.  Any objections
to doing that?
