Committed 0001-0005.
Thanks Robert.
I made a few further modifications. These were mostly cosmetic, but with two exceptions:
1. I moved one set_cheapest() call to avoid doing that twice for the top-level grouped_rel.
2. I removed the logic to set partition properties for grouped_rels. As far as I can see, there's nothing that needs this. It would be important if we wanted subsequent planning stages to be able to do partition-wise stuff, e.g. when doing window functions or setops, or at higher query levels. Maybe we'll have that someday; until then, I think this is just a waste of cycles.
OK.
Changes related to postgres_fdw which allows pushing aggregate on the foreign server is not yet committed. Due to this, we will end up getting an error when we have foreign partitions + aggregation.
Attached 0001 patch here (0006 from my earlier patch-set) which adds support for this and thus will not have any error.
