No, I use what initdb creates:

$ cat postgresql.conf | grep ^[a-zA-Z]
max_connections = 100                   # (change requires restart)
shared_buffers = 24MB                   # min 128kB or max_connections*16kB
max_fsm_pages = 153600                  # min max_fsm_relations*16, 6 bytes each
datestyle = 'iso, dmy'
lc_messages = '[EMAIL PROTECTED]'                      # locale for system 
error message
lc_monetary = '[EMAIL PROTECTED]'                      # locale for monetary 
lc_numeric = '[EMAIL PROTECTED]'                       # locale for number 
lc_time = '[EMAIL PROTECTED]'                          # locale for time
