Обсуждение: entries in serverlog file
Hi everybody,
I have, by default, on a linux machine, a file called
serverlog in the data directory, whose entries often
prove to be very useful. What would be even more useful
would be a timestamp along with each entry.
Is there any way I can add such timestamp at this point?
Perhaps via postgresql.conf file (also in the data directory)?
Thank you in advance.
Regards,
Tena Sakai

By all means, do read the documentation referred to by Joshua. For a quick starting point, we have found it useful to use these settings: redirect_stderr = on log_line_prefix = '[%m] %p %q<%u %d %r> '
Hi Joshua,
Hi Kevin,
Many thanks for your suggestions/advices.
I am reading chapter 17 of the manual, which in the hindsight,
I should have read a month ago. But this is very good. I am
making haste slowly.
Thanks again.
Regards,

Hi Everybody,
I have read chapter 17 of the current manual and learned
interesting options. But as I compare what's in the
postgresql.conf file to what I think I comprehend, I am
a slightly confused:
In the conf file I see log_destination is set as 'stderr'
and redirect_stderr is set as off AND they are both commented
out. Yet, I am accumulating log entries into serverlog file.
To me this is a fine default setting. So my question amounts
to be the following:
Can I just uncomment log_line_prefix entry and stick what I want
(such as %u, %d, %m, etc) into the quotes and expect to see the
logged lines be prefixed with username, database name, timestamp,
etc with all other things intact? I come from change-as-few-
things-as-possible-at-one-time-school.
Thank you in advance.

Sure; you will however regret by and by that you didn't turn on
redirect_stderr, because there is no way to rotate the logfile
(other than restarting the postmaster) when it's simply going straight
to stderr. The more verbose you make the log, the sooner its bulk is
going to become a problem...

Hi Tom,
Thanks. I will live a bit dangerously while I
strategize what to do with the logfile. I am
not sure if 7 day log rotation is really a
wise option for now. I will come up with
something fitting in time. Thanks for your
comment, nonetheless.
