syslog_sequence_numbers

doc html

<p>
         When logging to <span class="application">syslog</span> and this is on (the
         default), then each message will be prefixed by an increasing
         sequence number (such as <code class="literal">[2]</code>).  This circumvents
         the <span class="quote">“<span class="quote">--- last message repeated N times ---</span>”</span> suppression
         that many syslog implementations perform by default.  In more modern
         syslog implementations, repeated message suppression can be configured
         (for example, <code class="literal">$RepeatedMsgReduction</code>
         in <span class="productname">rsyslog</span>), so this might not be
         necessary.  Also, you could turn this off if you actually want to
         suppress repeated messages.
        </p><p>
         This parameter can only be set in the <code class="filename">postgresql.conf</code>
         file or on the server command line.
        </p>
