title: PostgREST error on connecting in AWS using secrets
body: <p>Currently deploying PostgREST in AWS. When I use Fargate and just hardcoded type in the environment variables for the connection string, the machine works like a charm.
  However I recently replaced these values with secrets. In the secret I copy-pasted the entire string in the value and in the environment variable I set the source from "Value" to "ValueFrom".</p>
  
  <p>So the value now is:</p>
  
  <pre><code>postgres://&lt;myuser&gt;:&lt;mypass&gt;@&lt;amazon-rds-instance&gt;:5432/&lt;db&gt;
  </code></pre>
  
  <p>When I use this connectionstring directly in the environment variable I can easily connect, so I know the information is correct.</p>
  
  <p>The logs come back with the following error:</p>
  
  <blockquote>
    <p>{"details":"missing \"=\" after \"{\"postgrest_db_connection\":\"postgres://myuser:mypass@amazon-rds-instance:5432/db\"}\" in connection info string\n","code":"","message":"Database connection error"}</p>
  </blockquote>
  
  <p>I also checked I have no characters in the string that need to be escaped. What can I be missing here?</p>
