It may still be worth selectively applying these techniques to writing out tuples, per my previous remarks (and the latest "Using quicksort for every external sort run" revision, which has a specialized version of this patch). I see real benefits there across a variety of situations on different hardware, and I'm hesitant to give that up without further analysis. However, I think that this patch is over as an independent piece of work -- there is too much of a mixed picture. I'm going to mark this patch "returned with feedback". -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
