Schema description is wrong for uri field in {file_managed} table

For this field of the {file_managed} table we currently have:

      'uri' => array(
        'description' => 'Path of the file relative to Drupal root.',
        'type' => 'varchar',
        'length' => 255,
        'not null' => TRUE,
        'default' => '',
      ),

This is clearly incorrect, since this is not what the uri field contains - it contains values like public://field/image/73gqrypy.jpg
