My concern here is EXPLAIN for foreign joins. I think it's another problem how we handle Foreign Scan plan nodes representing post-scan/join operations in EXPLAIN, so I'd like to leave that for another patch.
What is the post-scan/join operations? Are you saying EPQ recheck and alternative local join plan?
No. I mean e.g., aggregation, window functions, sorting, or table modification. In other words, Foreign Scan plan nodes created from ForeignPath paths created from GetForeignUpperPaths.
