I makes sense to me although until your email I didn't
know that's how postgres (or is it kernel) will assign jobs.
I was under the impression that if the loads get higher
kernel will automatically distributive "active" processes
to multiple cpus. Isn't that the case? I have the
same set up (mod_perl, apache dbi with postgres backend)
as you do and I am in the process of getting an smp box to run postgres

If your idea is the correct one I can think of artificially
loading postgres server at startup.....

Also bear in mind that modperl processes at front end got
periodically killed, new childs periodically born,
and new connections periodically re-established. (Assuming
you have reasonable apache config file) So
over the course of web server life time things should
work out. Hmm... I like this scenerio and feel
that things aren't as bad as I thought when I first
started to type this post.
