Minus a possible documentation update, 0003 seems almost ready, too.

For 0002, would adding vacuum_skip_rel() before and after
try_relation_open() in vacuum_rel() be enough?  That way, we could
avoid emitting an ERROR for only the VACUUM FULL case (and skip it
with a WARNING like everything else).
