I thought the point of INSERT ... ON CONFLICT update was so that you
didn't have to care if it was a new row or not?
If you do care, it seems like it makes more sense to do your own INSERTs
and UPDATEs, as Django currently does.
I wouldn't be *opposed* to having a pseudocolumn in the RETURNed stuff
which let me know updated|inserted|ignored, but I also don't see it as a
feature requirement for 9.5.
