Would this only affect RETURNING queries that are returning data via a
SRF? ISTM that pushing to a tuplestore is a lot of extra work for
simpler cases like INSERT INTO table DELETE FROM queue_table WHERE ...
RETURNING *; Even for the case of just going back to the client, it
seems like a fair amount of overhead.
