title: Upload only one table using heroku pg:transfer instead of whole database
body: <p>I'm able to push my database from my local machine to my heroku app with pg:transfer like this:</p>
  
  <p><code>heroku pg:transfer --from postgres://localhost/idx_map_development --to aqua</code></p>
  
  <p>But I don't want to upload the whole database, I only want to upload the properties table, is this possible using pg:transfer? If so how would the above line look?</p>
