title: Postgres dev in Heroku doesn't create any table
body: <p>I'm trying to deploy a basic java application with Postgres integration in Heroku. I've cloned this project <a href="https://github.com/heroku/devcenter-java-database" rel="nofollow">https://github.com/heroku/devcenter-java-database</a>. I was able to make the app work in a proper way locally. It creates a table called ticks within the database and a tuple is inserted in it.</p>
  
  <p>When I deploy the app to Heroku, it seems to work as well. In fact, it works. I can run a select query and get the right result. The strange thing comes up when I try to check my postgres db in Heroku. It seems nothing has been created. I don't know if it's caused because I have a Heroku's Dev plan. But I don't have any ideas why Heroku behaves different than my local env.</p>
  
  <pre><code>::term&gt;run "sh devcenter-java-database-plain-jdbc/target/bin/main"
    Running sh devcenter-java-database-plain-jdbc/target/bin/main attached to terminal...      up, run.6018
    Read from DB: 2013-02-03 12:51:42.110186
  </code></pre>
  
  <p>The app works, but it doesn't save anything in my Heroku db.</p>
  
  <pre><code>::term&gt;pg:info

  <p>Any ideas?</p>
