> Ordinals in GROUP BY or ORDER BY like "1" in "order by 1" or "group by 1" should be considered as unresolved before analysis. But in current code, it uses "Literal" expression to store the ordinal. This is inappropriate as "Literal" itself is a resolved expression, it gives the user a wrong message that the ordinals has already been resolved.
