See src/backend/catalog/pg_depend.c
/* * If the referenced object is pinned by the system, there's no real * need to record dependencies on it.
This saves lots of space in * pg_depend, so it's worth the time taken to check. */
Certainly, pg_catalog is pinned.
select * from pg_dependwhere refobjid = (select oid from pg_namespace where nspname
='pg_catalog') and refclassid = 'pg_namespace'::regclass;
classid | objid | objsubid | refclassid | refobjid | refobjsubid | deptype
