Well, this sure looks scary:
# maintenance_work_mem = 256MB  #webserver with 2GB RAM
But I'm amazed by this, too:
# max_connections = 700  # web application database
How many CPUs and spindles are you assuming there?
My testing and experience suggest applications should use no more than
4 per CPU plus 2 per spindle, absolute maximum.  Don't you find that a
connection pool with queuing capability is required for best
performance with a large number of users?
