It seems to me that it would be simple enough to write a script to do that to avoid any other noise: allocate an array with N random elements, and fetch the M-th element from it after applying a sort method. I highly doubt that you'd see much difference with a low number of elements, now if you scale at a thousand standbys in a quorum set you may surely see something :*) Anybody willing to try out? -- Michael -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
