> Test *topnkey_grouping_sets* fails intermittently.
> Queries which project 2 columns but order by only one of them can have more
> than one good result set:
> {code:java}
> CREATE TABLE t_test_grouping_sets(
> a int,
> b int,
> c int
> );
> INSERT INTO t_test_grouping_sets VALUES
> (NULL, NULL, NULL),
> (5, 2, 3),
> (10, 11, 12),
> (NULL, NULL, NULL),
> (NULL, NULL, NULL),
> (6, 2, 1),
> (7, 8, 4), (7, 8, 4), (7, 8, 4),
> (5, 1, 2), (5, 1, 2), (5, 1, 2),
> (NULL, NULL, NULL);
> SELECT a, b FROM t_test_grouping_sets GROUP BY GROUPING SETS ((a, b), (a),
> (b), ()) ORDER BY a LIMIT 10;
> {code}
> {code:java}
> 5 NULL
> 5 2
> 5 1
> 6 2
> 6 NULL
> 7 8
> 7 NULL
> 10 NULL
> 10 11
> NULL 1
> {code}
> {code:java}
> 5 NULL
> 5 2
> 5 1
> 6 2
> 6 NULL
> 7 8
> 7 NULL
> 10 NULL
> 10 11
> NULL NULL
> {code}
> Since we don't order by *b* both result sets are valid.
