title: "Can't locate PgCommon.pm" when trying to uninstall Postgres server
body: <p>I'm trying to remove <code>postgres</code> from my Ubuntu machine, but when I do, I'm getting the error message</p>
  
  <pre><code>Can't locate PgCommon.pm (@INC is [... a list of paths ...])
  </code></pre>
  
  <p>Any idea why PostgreSQL would lose track of a file it installed itself?</p>
