I noticed that pg_verify_checksum takes an "-o oid" argument to only
check the relation with that OID; but that's wrong, because the number
is a relfilenode, not an OID (since it's compared to the on-disk file
name).  I would suggest changing everything to clarify that it's a
pg_class.relfilenode value, otherwise it's going to be very confusing.
Maybe use "-f filenode" if -f is available?
