--disable-triggers in 7.x is a crude hack that works by munging the
system catalogs (specifically pg_class.reltriggers). You need to
un-munge the catalog entries in the way that pg_restore evidently
didn't have a chance to do.

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