Are you using pg_pconnect, or pg_connect?

pg_pconnect is not simple connection pooling, and can quickly run your
machine / apache server / postgresql server out of resources if improperly
configured.

It's best to reduce the max apache children to something like 30 or 40 and
increase postgresql to about 100 in this situation.

but for most people, persistant connects are no great advantage.  On my
Dual PIII-750 server, I can create about 1,000 non-persistant connects a
second, while I can create 1,000,000 persistant connections a second.
Considering I can only server about 200 to 300 pages a second, the speed
of connection is pretty much below the level of noise on this system,
whether they be persistant or not.
