title: Getting my postgresql db version?
body: <p>On SQlite I could do a query for <code>PRAGMA user_version;</code> and I could set the version if need be too.  Is there anything in postgres that could do the same thing? </p>
  
  <p>I tried <code>select version()</code> but that gets the literal version of postgres, and not a custom set version.</p>
  
  <p>As an update: I researched commenting on databases. Perhaps this could be solution... <a href="https://www.postgresql.org/docs/9.1/static/sql-comment.html" rel="noreferrer">commenting docs</a></p>
