title: Stopping postgresql from starting on ubuntu startup
body: <p>Ubuntu 16.04.1 LTS
  I have tried:</p>
  
  <pre><code>sudo update-rc.d -f postgresql remove
  </code></pre>
  
  <p>and</p>
  
  <pre><code>sudo vim /etc/postgresql/9.5/main/start.conf
  </code></pre>
  
  <p>then i change the word "auto" to "disabled"</p>
  
  <p>Then i reboot the computer, and when it starts, i login and do:</p>
  
  <pre><code>sudo service --status-all | grep postgresql
  </code></pre>
  
  <p>Which returns:</p>
  
  <pre><code>[ + ]  postgresql
  </code></pre>
  
  <p>So it is still starting when the server starts.
  What is left for me to do? I don't want this service running when the computer starts, only when i manually start it with:</p>
  
  <pre><code>sudo service postgresql start
  </code></pre>
