Just confirmed what @hvanhovell said, Netezza and Terradata support "group
by position".

Also confirmed what @rxin said, in Group By, the position is based on the
output columns (select expression).
Thus, I think the integer in `groupingExpressions` should be resolved based
on `aggregateExpressions` of `Aggregate`. Please let me know if my
understanding is wrong. Thanks!
