Thanks for getting to this so quickly. If you're processing the quals
remotely, but not remove them from the list of quals to be checked
locally by the executor, you're fine. If you are checking them
remotely *instead of* locally, then you need to make some changes that
should look similar to what the patch changed in postgres_fdw.
