--
-- Test that partitioned-index operations cope with objects that are
-- not in the secure search path.  (This has little to do with seg,
-- 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.
