Anyway, is this spawning being done by postmaster or webserver or both? If postmaster, does an application-level persistent connection request communicate itself directly to the postmaster, and can the postmaster keep track of its spawning? Also, at some crude level, if I were to direct every alternate connection to a different install box of postgresql, won't that help with *some* load-balance? Cheers, Bill
