## Which issue does this PR close? - Closes #20443. ## Rationale for this change This change fixes #20443, and adds support for generating dynamic filters for the left and right sides of a `SortMergeJoin`, in order to allow for range-based pruning of both sides of the join. Some consumers of the dynamic filter may even be able to seek/skip ahead on their inputs. ## What changes are included in this PR? To allow `SortMergeJoin` to actually propagate dynamic filters down to scans and get things working end to end, it was necessary to fix the `handle_child_pushdown_result` implementations of a variety of nodes which were failing to clone and update themselves. ## Are these changes tested? Yes. ## Are there any user-facing changes? Explain will now show dynamic filters for `SortMergeJoin`, and for the scans that they consume. -- This is an automated message from the Apache Git Service.
