Hm. You're sure you're looking at pg_class in the right database?
If there really isn't a pg_class entry matching that relfilenode,
then the files are orphans and can be removed. There are some scenarios
where orphan files can be left behind, but they generally involve
database crashes ... have you had any of those?
