   This is because the completion of the constant column in our implementation is in aggNode. The calculation of rollup repetition is done between scanNode and agg, so the constant cannot be repeated correctly. This problem is difficult to solve under our current framework. I think Refactor the implementation of grouping set to solve this problem
