Huh? That's rather strange. No code from that patch is even exececuted
until the alter_table regression tests way later. So I can't see how
that patch could cause the matview error. Which is pretty clearly using
an freed relcache entry.
I think this may be a timing issue.

The alter table failure lateron seems to be "ERROR: relation "tmp"
already exists", which just seems to be a consequence of incomplete
cleanup due to the earlier crashes.
