FYI, location of postgres.conf at /var/lib/pgsql/data/postgres.conf
many thanks..
I added the following to FreeBSD:
/etc/newsyslog.conf:
/var/log/postgresql 600 7 * @T00 JC
/etc/syslog.conf:
local0.* /var/log/postgresql
/usr/local/pgsql/data/postgresql.conf:
log_destination = 'syslog'
syslog_facility = 'LOCAL0'
syslog_ident = 'postgres'
log_min_duration_statement = 100 # -1 is disabled, 0 logs all
statements, in ms.
Remember to touch /var/log/postgresql before restarting syslogd (kill
-HUP syslog-pid). Chmod 0700 so only root can read the log-file.
Adjust log_min_duration_statement to your needs.
I found this recipe somewhere, but don't remember where so I can't
give credit to the that person.
Hello,
another possibility is to have logs stored in a file by just changing
'redirect_stderr' to 'on' and 'log_destination' to 'stderr'.
This way, with the default config, all logs sent to stderr will be written
to 'log_directory' under the name 'log_filename', without having to change
syslog.conf (you just need to change postgresql.conf).
Additionaly, I added 'log_rotation_size = 0' to have on log file per day.
Note that in that case, the log files won't be rotated, you'll need to
check you don't store too many log file after a few months (as the number
of files will increase every day).
