title: psql: FATAL: too many connections for role
body: <p>I tried connecting to the database server using the command:</p>
  
  <pre class="lang-sh prettyprint-override"><code>psql -h host_ip -d db_name -U user_name --password
  </code></pre>
  
  <p>It displays the following line and refuses to connect.</p>
  
  <pre class="lang-sh prettyprint-override"><code>psql: FATAL:  too many connections for role "user_name".
  </code></pre>
  
  <p>How to close the active connections?<br>
  I do not have admin rights for the database. I am just an ordinary user.</p>
