> Residual predicates are evaluated after finding matches using equality
> condition on key columns, but before deciding whether an input had a match
> for the join and resolving outer references. They allow to implement in a
> simple (but potentially inefficient) way inequality predicates that accompany
> equality predicates in join condition.
