[ shudder ] I can see the complaints now: "Merely starting up Postgres cut my overall system performance by a factor of 10! I wasn't even using it!! What a piece of junk!!!" I can hardly think of a better way to drive away people with a marginal interest in the database... This can *not* be default behavior, and unfortunately that limits its value quite a lot. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
