We are using the defaults for these values. Keep in mind we are allowing 
between 5-50 max connections per postmaster.  Here is an example of our 
largest database. It is 7.9GB we allow 50 max connections and the 
buffers are set to 16000/125MB. This is our master database and it has a 
lot of activity as compared to the other databases. We run VACUUM at 
midday VACUUM FULL at night, VACUUM ANALYZE on weekends.

Thanks
