Well, the logic is the same all the way back, but the code has changed textually quite a bit since 7.4 and even more since 7.3. I think the patch would apply reasonably cleanly to 8.0, but adjusting it for 7.x will take a bit of work, which would mean those versions would probably need to be reviewed separately. One possible compromise is to use this patch in 8.x and a simpler patch in 7.x --- people who are very concerned about performance ought to be running 8.x anyway ;-) regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
