I realized possibly people were thinking of that as a "feature" and not a
bugfix for backpatch (?)
But, my issue is a query which worked under v11 PWJ but fails under v12
(apparently broken by d25ea01275).
In my mind, if the planner doesn't support that query with PWJ, I think it
should run without PWJ rather than fail.
