Hello I found a break in GROUPING SETS implementation. Now I am playing with own executor and planner node and I can't to go forward :(. Probably this feature will need a significant update of our agg implementation. Probably needs a some similar structure like CTE but it can be a little bit reduced - there are a simple relation between source query and result query - I am not sure, if this has to be implemented via subqueries? The second question is relative big differencies between GROUP BY behave and GROUP BY GROUPING SETS behave. Now I don't know about way to join GROUP BY and GROUPING SETS together
