Pushed with a little bit of fooling about. After looking at the
git history, I saw that the Assert we were wondering about used to
be just "Assert(constr)", and there were not run-time checks on
whether constr is null. That was changed when f0e44751d added
partition constraint checking into ExecConstraints' responsibilities.
At some later point that code was removed from ExecConstraints,
but we failed to undo the other changes in ExecConstraints, leaving
it looking pretty silly. So I reverted this to the way it was,
with just an Assert and no regular checks.
I also did a bit more work on the comments. (Speaking of which,
is there a better place to put the commentary you removed from
InitResultRelInfo? It was surely wildly out of place there,
but I'm wondering if maybe we have a README that should cover it.)
I pushed this to HEAD only, and the other patch as far back as
v12, so we will have a solution to the deadlock problem in v12.
