I've followed the threads of needing to run vacuum nightly, and even got an answer to a slow updating database regarding needing to vacuum. But I haven't see the question asked: is it possible to completely turn off the revision tracking feature so that vacuum does not need to be run at all? Thanks for any pointers, Mike ---------------------------(end of broadcast)--------------------------- TIP 6: Have you searched our list archives? http://www.postgresql.org/search.mpl
