No. IIRC, a patch for that was submitted, and rejected because no significant performance improvement could be demonstrated. We don't have enough information about the actual on-disk layout to be very intelligent about this, so it's better to just issue the writes and let the OS sort them. regards, tom lane -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
