pg_dump never dumps system objects, so I don't see a need for a switch to tell it not to.
I considered pg_class to be a system object, which was dumped under -t '*'
$ pg_dump -U postgres --schema-only -t '*' | grep 'CREATE.*pg_class' CREATE TABLE pg_catalog.pg_class ( CREATE UNIQUE INDEX pg_class_oid_index ON pg_catalog.pg_class USING btree (oid); CREATE UNIQUE INDEX pg_class_relname_nsp_index ON pg_catalog.pg_class USING btree (relname, relnamespace); CREATE INDEX pg_class_tblspc_relfilenode_index ON pg_catalog.pg_class USING btree (reltablespace, relfilenode);
