which is spawned by the postmaster upon connection.
Thanks Joshua and Thomas. I guess my ignorance is showing :). 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
