This is surely a good start.  We could optimize this even more by saying, disk 
space is cheap, so let's just use a much higher default setting for 
checkpoint_segments.  (If PostgreSQL is installed but not actually used, not 
all the space is actually going to be used anyway.)  Then, increase 
max_connections a bit; that should be OK for most users.  Then you are left 
with the memory settings, and those need kernel tuning in most cases, so any 
automation tool loses.  Hmm.
