> This patch fixes two cases of expression projection bugs. Please take a look at two example cases:
> The point of this case is outer join and constant expression.
> {code}
> select c_custkey, o.o_orderkey, 'val' as val from customer left outer join (select * from orders) o on c_custkey = o.o_orderkey
> {code}
> The point of this case is non-column grouping keys.
> {code}
> select upper(lower(l_orderkey::text)) as key, count(1) as total from lineitem group by upper(lower(l_orderkey::text)) order by upper(lower(l_orderkey::text)), total;
> {code}
