cache_admin_menu missing in database. Can I recreate it?

I have installed admin_menu some time back and recently schema module showed that cache_admin_menu table is missing in my database. I checked system table and noticed that schema_version is 7304 which is correct. I am wondering how Drupal didn't create cache_admin_menu table in my database. However is it safe to execute following script to create cache_admin_menu by my own? Following code is copied from admin_menu.install

//cache_admin_menu does not exists in database
if (!db_table_exists('cache_admin_menu')) {
    $schema = drupal_get_schema_unprocessed('system', 'cache');
    db_create_table('cache_admin_menu', $schema);
  }
