I accept the "run from init.d" argument. So then, is there a case for 
increasing the limits that initdb works with, to reflect the steep rise 
we have seen in typically available memory at the low end? We currently 
try {100, 50, 40, 30, 20, 10} for connections and {1000, 900, 800, 700, 
600, 500, 400, 300, 200, 100, 50} for buffers. I think there's arguably 
a good case for trying numbers several (4 maybe?) times this large in 
both categories. Out own docs state that the default number of shared 
buffers is low for efficient use, and it would be nice to try to allow 
one connection per standard allowed apache client (default is 256 
non-threaded and 400 threaded, I think).
