Oh, here it is --- should have checked the spelling of the pg_class
field:
		elog(ERROR, "relation \"%s\" has reltriggers = 0",
			 RelationGetRelationName(rel));

The most likely bet is that a failed pg_restore left the relation's
triggers disabled.  You can fix this by doing what the restore should
have done:

UPDATE pg_catalog.pg_class SET reltriggers = 
(SELECT count(*) FROM pg_catalog.pg_trigger where pg_class.oid =
tgrelid) 
FROM pg_catalog.pg_namespace 
WHERE relnamespace = pg_namespace.oid AND nspname !~ '^pg_';
