DB::ULists: Greatly improved query performance for VN list with 'hide voted'
Crawlers would often find such pages, and the query would often take more than a second to finish, in some extreme cases even 10 seconds. This fix converts an intermediate result into an array, forcing the query planner to evaluate the subquery first, resulting in a far more optimal query plan.
