title: Alembic Downgrade,Upgrade,Revision and Migrate are doing nothing
body: <p>EDIT: This apparently is effecting trying to upgrade or create a new revision file as well. </p>
  
  <p>I've been trying to run a downgrade in Alembic, which I have gotten to work before, with no luck. My current revision ID never changes and I was wondering if anyone could help me figure out why?
  It's not like I am getting an error or any kind of message that might help me understand what is going wrong. All I see is the following</p>
  
  <pre><code>INFO  [alembic.runtime.migration] Context impl PostgresqlImpl.
  INFO  [alembic.runtime.migration] Will assume transactional DDL.
  </code></pre>
  
  <p>Things I've tried:  Just running downgrade, downgrade -1, downgrade -5, downgrade 'revision_id'. 
  All other commands (like show) appear to be working as expected, so I honestly have very little to go on. </p>
  
  <p>Know I'm no expert with Alembic, so I'm likely missing something simple. </p>
  
  <p>Thanks in advance.</p>
