Are you sure? I've heard of at least one installation which runs with
5000+ connections, and it works fine. (you know who you are - I don't
know if it's public info, so I can't put out the details - but feel free
to fill in :P)
That said, there's certainly some overhead, and using pgpool if possible
is good advice (depending on workload). I'm just wondering about
the "dramatically" part.
