title: template0 and template1 database dropped accidently
body: <p>I did not know that <code>template0</code> and <code>template1</code> database templates are required in order to create empty databases. I deleted them in order to clear up postgres. Now I'm not able to create any new database. Gives me this error :</p>
  
  <pre><code>ERROR:  template database "template1" does not exist
  </code></pre>
  
  <p>What can I do to get things going once again. I'll be very thankful for any help.</p>
