-- Test that partitioned-index operations cope with objects that are

-- but we need an opclass that isn't in pg_catalog, and the base system
-- has no such opclass.) Note that we need to test propagation of the
-- partitioned index's properties both to partitions that pre-date it
-- and to partitions created later.
