title: Query progressbar in sqlite and python
body: <p>I want to create a progressbar for queries, say i have a query that will take 40 seconds, i'd like to give some feedback to users on how long this will take and i found this code from oracle that is exactly matches what i want. Is there a same thing in sqlite?</p>
  
  <pre><code>from timemachine import oracle
  
  guesser=oracle(guess="SQL")
  guesser.set_hint(driver="pypgsql")
  guesser.set_hint(gui="wx")
  
  expected_runtime=guesser.estimate("&lt;put your query text here&gt;")
  </code></pre>
