+ On most Unix systems, you will need to alter the configuration of

+ to make use of the <systemitem>syslog</systemitem> option for
+ <varname>log_destination</>. <productname>PostgreSQL</productname>
+ can log to <application>syslog</application> facilities
+ <literal>LOCAL0</> through <literal>LOCAL7</> (see <xref
+ linkend="guc-syslog-facility">), but the default
+ <application>syslog</application> configuration on most platforms
+ will discard all such messages. You will need to add something like
+<programlisting>
+local0.* /var/log/postgresql
+</programlisting>
+ to the <application>syslog</application> daemon's configuration file
+ to make it work.
