   @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.
