This is forgetting about materialized views, which is something that
pg_upgrade would also complain about when checking for relations with
aclitems. As far as I can see, the only place in the main regression
test suite where we have an aclitem attribute is tab_core_types for
HEAD and the stable branches, so it would be enough to do this
change. Anyway, wouldn't it be better to use the same conditions as
the WITH OIDS queries a few lines above, at least for consistency?
Note that check_for_data_types_usage() checks for tables, matviews and
indexes.
