I just realized that you were actually talking about the waste of space in workers here, as opposed to the theoretical waste of space that would occur in the leader should there ever be a parallel randomAccess tuplesort caller. To be clear, I am totally against allowing a waste of logtape.c temp file space in *workers*, because that implies a cost that will most certainly be felt by users all the time. -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
