It's actually entirely normal. For some system tables the actual relfilenode isn't stored in the system catalog but in the relation mapper. Those are a) tables needed to access the catalogs themselves like pg_class, pg_attribute, pg_proc, .. b) shared tables where we otherwise couldn't change the relfilenode from another database
To get the actual relfilenode you actually need to do something like: SELECT relname, pg_relation_filenode(pg_class.oid) FROM pg_class;

Dear Andres
You are right, Some tables are mapped, and some other are global.
