Hmm. I think we generally allow ALTER TABLE to work on non-table
relations. For example, ALTER TABLE .. OWNER TO happily accepts a
view or materialized view as an argument. I have had my doubts about
that policy from time to time (cf.
1489e2f26a4c0318938b3085f50976512f321d84) but it does seem to be the
policy (cf. b14206862278347a379f2bb72d92d16fb9dcea45). Is there some
reason to think that the same policy that we apply to ALTER should not
also apply to DROP?
