   @kosiew 's suggestions look good to me, I have one another question:
   
   **FilterPushdownPhase::Pre**
   IMO, `FilterPushdownPhase::Pre` runs before most other physical 
optimizations, It only handles "static filters that do not reference any 
ExecutionPlans", this type of static filter pushdown should logically belong in 
the logical optimization phase. 
   
   Is there a duplication with `push_down_filter` in the logical optimizer?
