title: Level DB data store gets recreated everytime
body: <p>I am new to web app development, and still learning the basics. I am working on a basic application with nodejs and level db. Every time I restart my web application, the leveldb data store gets recreated, and the data that was stored in it is all gone. </p>
  
  <p>My example code is below:</p>
  
  <pre><code>var level = require ('level');
  var db = level('./mydb.db', {createIfMissing : true});
  </code></pre>
  
  <p>My understanding is that the db will get created only if it is missing.. otherwise the existing db would be used. In my case that is not happening.. what am I doing wrong?</p>
