Yes, I have some files which is not in pg_class.relfilenode of any table or index.
I want to know which table or index stored in such files.
From that page:
Each table and index is stored in a separate file. For ordinary relations, these files are named after the table or index's filenode number, which can be found in pg_class.relfilenode.
