Syslog v/s filename in pg_ctl command

Hello All,

When we pass file name in pg_ctl (with option -l) what has to be syslog
value..
Should it be enabled..?if so what cud be the value for syslog..?

Though I have sent approprite file name with -l option ,and if I use
default value for syslog (0) then
I am getting the messages in console..

So how can I override getting messages in console...?


Thx in advance,
Prasanna.
