I tend to agree with Andres on this one.  This feels a bit like
accepting a command but then not actually following-through on it
if it turns out we can't actually do it.  If it's truely an optimization
(and I suspect my other email/question might provide insight into that),
then it should be something we can 'just do' without needing to be asked
to do it, along the same lines of not WAL'ing when the appropriate
conditions are met (table created in this transaction, etc, etc).
Thanks,
