tgargs, not tgnargs.

Hmph. Those should be 'i' references to the foreign key constraint,
not 'a' references to the relations. I suspect this database was
carried forward from an ancient (pre-7.3) dump that defined the triggers
by "CREATE CONSTRAINT TRIGGER" instead of "ALTER ADD FOREIGN KEY".
Have you ever run contrib/adddepend to update the definitions to be
proper constraints?
