I've posted on this before once or twice. Basically, whatever Apache's
max children is set to, postgresql to be set for a higher number of
connections. since apache defaults to a much higher number, it's a
problem looking to happen.
If you drop the max apache children to say 64 and crank the max
connections on pgsql to 128 or so, it'll work fine.
