Look through the system catalogs to find the object(s) that claim to be in that namespace, and then tell us what they are and their history. select * from pg_type where typnamespace = 16396 and likewise for pg_class.relnamespace, pg_operator.oprnamespace, pg_conversion.connamespace, pg_opclass.opcnamespace, pg_aggregate.aggnamespace, pg_proc.pronamespace. regards, tom lane
