The regression test for this patch (in aggregate.sql) succeeds. So I am closing this bug.

> Wrong result from select when aliasing to same name as used in group by. Example:
> If we have the following table:
> ij> select * from tt;
> I |J
> -----------------------
> 1 |2
> 2 |3
> 1 |2
> 2 |3
> 2 |3
>
> 5 rows selected
> The following select is ok:
> ij> select i, count(*) as cnt from tt group by i;
> I |CNT
> -----------------------
> 1 |2
> 2 |3
>
> 2 rows selected
> But this one returns wrong result in the aliased column:
> ij> select i, count(*) as i from tt group by i;
> I |I
> -----------------------
> 1 |1
> 2 |2
>
> 2 rows selected
