> Currently if there are no stats hive bails out of cbo and try non-cbo route.
> Since most of the subqueries are only supported in CBO and not in non-cbo we
> end up with completely different error message. This creates confusion.
> One possible solution is to throw warnings that stats are missing before
> throwing subquery related error message.
