The handling of nulls in grouping set results is a bit icky, see prepare_projection_slot in nodeAgg.c. The comment there lists a number of assumptions which may or may not hold true under JIT which might give a starting point to look for problems. (Unfortunately I'm not currently in a position to test on a JIT build) (This wasn't my first choice of approach; originally I had a GroupedVar node that evaluated either as the Var would or to NULL instead, and put that into the projection. However there was a lot of resistance to this approach at the time, and the new node idea was abandoned in favour of poking directly into the slot.) -- Andrew (irc:RhodiumToad)
