title: Django 1.8 error: No database fixture specified
body: <p>I was using an <code>sqlite</code> database and after applying <code>python manage.py dumpdata</code> I added the new <code>postgresql</code> database settings in <code>settings.py</code></p>
  
  <pre><code>DATABASES = {
  'default': {
      'ENGINE': 'django.db.backends.postgresql_psycopg2',
      'NAME': 'music',                      
      'USER': '**',
      'PASSWORD': '****',
      'HOST': '127.0.0.1',
      'PORT': '5432',
      }
    }
  </code></pre>
  
  <p>But when I try to load the data into the new <code>postgresql</code> database I get the following error</p>
  
  <pre><code>C:\Users\Saket\musicalguru&gt;python manage.py loaddata
  usage: manage.py loaddata [-h] [--version] [-v {0,1,2,3}]
                        [--settings SETTINGS] [--pythonpath PYTHONPATH]
                        [--traceback] [--no-color] [--database DATABASE]
                        [--app APP_LABEL] [--ignorenonexistent]
                        fixture [fixture ...]
  manage.py loaddata: error: No database fixture specified. Please provide the  path of at least one fixture in the command line.
  </code></pre>
  
  <p>Can't understand what the error is. I already have data in my <code>sqlite</code> database so I need the new data in the <code>postgresql</code> database too.</p>
