> running
> {code}
> drop table if exists tx1;
> create table tx1 (a integer,b integer,c integer);
> select sum(c),
> grouping(b)
> from tx1
> group by rollup (b);
> {code}
> returns 0 rows; however
> according to the standard:
> The <empty grouping set> is regarded as the shortest such initial sublist.
> For example, “ROLLUP ( (A, B), (C, D) )”
> is equivalent to “GROUPING SETS ( (A, B, C, D), (A, B), () )”.
> so I think the totals row (the grouping for {{()}} should be present) - psql
> returns it.
