I completely agree.  I think it's considerably premature to wrap a
beta at this point.  We haven't resolved the issue of what to do about
accidental restores into pg_catalog either; nobody replied to my last
email on that thread.

I would like to rip out the whole notion of whether a materialized
view is scannable and am happy to do that on Monday if you're willing
to sit still for it.  I think that's better than failing to support
unlogged relations, and I'm confident that the decision to put the
scannability flag in pg_class rather than the backing file is dead
wrong.  At the same time, I *also* agree that using the file size as a
flag is untenable.

I think it's pretty darn clear that we should change the algorithm,
and I think we've got a patch to do that.  So we should be able to
resolve this relatively quickly.  But +1 for adding a checksum
algorithm ID to pg_control anyway.

I have been assuming that Alvaro was responsible for fixing this since
he (AIUI) was the one who committed what broke it.  If that's not the
case, I should probably jump in, since I committed some earlier event
trigger patches.  Or Dimitri, as the original author of said patches.
