    Since its likely undecidable to generally determine if two given plans will produce the same results, it is okay for this function to return false, even if the results are actually the same. Such behavior will not affect correctness, only the application of performance enhancements like caching. However, it is not acceptable to return true if the results could possibly be different.

    This method can be overridden by any child class of QueryPlan to specify a set of constraints based on the given operator's constraint propagation logic.

    This method can be overridden by any child class of QueryPlan to specify a set of constraints based on the given operator's constraint propagation logic. These constraints are then canonicalized and filtered automatically to contain only those attributes that appear in the outputSet.
