> select min(employee_id), max(employee_id) from cp.`employee.json`;
> +------------+------------+
> | EXPR$0 | EXPR$1 |
> +------------+------------+
> | 1 | 1 |
> +------------+------------+
> In the above query we return the same result for both Min and Max. This seems
> to be related to multi phase aggregate not picking the correct ordinal.
