I am not saying to allow other things. I am just replying to your question that why can't we use PQsetSingleRowMode. I mean to say that one can fetch the data parallelly via the usage of cursors (by having restrictions like don't allow other parallel unsafe statements) in plpgsql. -- With Regards, Amit Kapila.
