title: psql 9.1 reset size of the postgresql log file
body: <p>My log file (postgresql-9.1-main.log) size use to be 3G  before rotation but a fews days ago it started to be 70G. I did not change anything.</p>
  
  <pre><code>pg_lsclusters   
  Version Cluster   Port Status Owner    Data directory                     Log file   
  9.1     main      5432 online postgres /var/lib/postgresql/9.1/main       /var/log/postgresql/postgresql-9.1-main.log   
  </code></pre>
  
  <p>So the log is not managed by PostgreSQL, but by the package since all the line related to the logging are commented out.</p>
  
  <p>Is it possible that PostgreSQL Common relies on logrotate?
  How can i reset the size of the log file to 3G?</p>
