Обсуждение: Logging PostgreSQL output

Hi all,

I want to log all PostgreSQL's output in a seperate file. Is it possible to use the syslog system to do that or is the
onlyway to use the stdout method? If it is possible to use the syslog system, how should I do this (I have tried
severalthings but nothing I tried worked)?

You should be able to configure your syslog daemon to do that; read
its man page.

This remark was what did it (all the other things allready were in place). Thanks. It is in the man pages but just as
anommission of file sync flag.

put these lines on your postgresql.conf

syslog = 2
syslog_facility = 'LOCAL0'
syslog_ident = 'postgres'

after this you have to configure your syslogd:

add these lines on yout syslog.conf:

# Postgres
LOCAL0.*                                      -/var/log/postgresql.log

not forget to add LOCAL0.none in your  /var/log.messages log ad
ad that "-" char in front of your file location log


now you have to SIGHUP both postgres and syslogd.
