Ensure pg_filenode_relation(0, 0) returns NULL. Previously, a zero value for the relfilenode resulted in a confusing error message about "unexpected duplicate". This function returns NULL for other invalid relfilenode values, so zero should be treated likewise.
It's been like this all along, so back-patch to all supported branches.
