Here is an updated version of this patchset. I've run pgindent for it, and also tweaked the commit messages a bit. In principle, 0001 can be backpatched to all supported versions to fix the cases where there are subqueries in the grouping expressions; 0002 can be backpatched to 16 where we have the nullingrels stuff. But both patches seem to be quite invasive. I'm not sure if we want to backpatch them to stable branches. Any thoughts about backpatching? Thanks Richard
