an index over (gil_wiki, gil_page_namespace_id, gil_page_title) would be very helpful, since it would allow listing all images used on a given page without knowing the page's id. This is esxpecially important if retrieving image usage on several pages on different wikis. Without this index, it would require one query per wiki. If this index is added, it can easily and efficiently be done with a single query.
