For [a fairly popular and important user tool](https://en.wikipedia.org/wiki/User:Ebrahim/ArticleTranslator.js), (check its use [here](https://en.wikipedia.org/w/index.php?title=Special:Search&limit=500&offset=0&profile=all&search=%22ArticleTranslator.js%22&searchToken=5xsnnycwhvfxub5ld2i4prjrc)) I need to query Wikipedia database about backlinks of a page but it seems unlike [Wikipedia servers](https://github.com/wikimedia/mediawiki/blob/master/includes/api/ApiQueryBacklinks.php#L286), labs replica doesn't have that access to that indexed table.
For example run this on ckbwiki_p on labs:
SELECT COUNT(*) FROM pagelinks WHERE pl_title="Main_page";
Then try to do the same on fawiki_p or enwiki_p (you will get stuck and timeout on large databases).. Can you please provide that index to labs users? Thanks
