Yes. this one line is the fix and the rest is testability -- in retrospect, the immediate testability issue was that the fake after-the-fact implementation of table partitioning provided through PlannerTestAideDeCramp avoided this bug by avoiding this functionaility -- partitioning was never propagated from base table to view. The view partitioning would have to have been specified separately, manually, in the test -- in which case the real code would go untested. I'm still not sure where the new regression is coming from -- related to sysproc permissions AFAICT -- I thought maybe that I had re-ordered the groups/roles code but it appears to be getting run in its original sequence, so I'm not seeing what could have changed.
