Oh, and here comes lapwing: - regression_slot | 1 | 12 + regression_slot | 1 | 10 So if it weren't that prairiedog showed 11 not 10, we'd have a nice neat it-depends-on-MAXALIGN theory. As is, I'm not sure what all is affecting it, though MAXALIGN sure seems to be a component. (locust seems to be AWOL at the moment, so I'm not holding my breath for that one to report in.) regards, tom lane
