@alamb I am wondering if you think it would be the solution to introduce
this boolean optimization (Distributivity of and over or):
(p and q1) OR (p and q2) should be replaced by p AND (q1 or q2)
p in this example could be our join predicate.
After this optimization, the physical planner should be able to see the
predicate in the filter.
