No. But it gave me another idea. Perhaps equally infeasible, but I don't see why. What if there were a map of modified pages. So every time any tuple was marked deleted it could be marked in the map as modified. VACUUM would only have to look at these pages. And if it could mark as free every tuple that was marked as deleted then it could unmark the page. The only downside I see is that this could be a source of contention on multi-processor machines running lots of concurrent update/deletes. -- greg ---------------------------(end of broadcast)--------------------------- TIP 6: Have you searched our list archives? http://archives.postgresql.org
