I'd also check on how your web server connects to Postgres. If you're using
a webserver that pools database connections (e.g. Apache with mod_perl and
DBI, AOLserver,IIS) you should be able to handle a large amount of web
traffic while maintaining only a few backend connections. If you're using
CGI, consider that each CGI program establishes its own connection to the
database and allocate resouces accordingly.

I'm smarter than average. Therefore, average, to me, seems kind of stupid.
People weren't purposely being stupid. It just came naturally.
