Description
Instead of evaluating predicates inside an unnest it would be better to push the predicates directly into the scanner that fills the “list of tuples” slot consumed by the unnest. For example, the predicate evaluation could be integrated into the scanner’s DFA for projecting complex input data to the minimal output tuple.
