No objections from me - if you want me to do one final round of review after the rebase (not sure how invasive it'll turn out), let me know.
Rebased patch is attached. Incremental sort get used in multiple places
of partition_aggregate regression test. I've checked those cases, and it seems
that incremental sort was selected right.
BTW one detail I'd change is name of the GUC variable. enable_incsort seems unnecessarily terse - let's go for enable_incremental_sort or something like that.
Already enable_incsort was already renamed to enable_incrementalsort since [1].
