It only works on mysql and MyISAM tables, so it's only really relevant for drupal 6. It is similar to http://drupal.org/project/db_maintenance but differs in that this is only a drush extension. This is handy because it does not make any drupal installation bigger and it can be run for many sites on the same server with only 1 installation.
