FWIW I hope so. It's a nice patch.
I'm trying to to whisk dust. Rebased version of patch is attached. This patch isn't passing regression tests because of plan changes. I'm not yet sure about those changes: why they happens and are they really regression?
Since I'm not very familiar with planning of INSERT ON CONFLICT and RLS, any help is appreciated.
Planner regression is fixed in the attached version of patch. It appears that get_cheapest_fractional_path_for_pathkeys() behaved wrong when no ordering is required.
