You can find the dependent objects with:
SELECT t.relname AS catalog, d.objid AS oid_dependent
FROM pg_catalog.pg_class t JOIN
pg_catalog.pg_depend d ON (t.oid = d.classid)
WHERE refobjid = 100456;
This will give you a list of system catalog tables and OIDs.
You can find out more about an dependent object by searching
for the OID in the system catalog.
