Re: postgresql having trouble under load

It sounds like you are using pg_pconnect.  First, try using pg_connect and
see if it can handle the load.  If it can't, write back and I'll tell you
how to configure apache / php / postgresql to handle the load you want
with pg_pconnect.   pg_pconnect is dangerous, and pg_close will NOT close
its connections, ever.
