Lack of interest Add index for user_id and post_date in xf_post table

[TickTackk]

Currently when running this query:

SELECT MAX(post_date) AS last_post_date, user_id, post_id
FROM xf_post
ORDER BY last_post_date
LIMIT 500

when xf_post has roughly a million rows, the query time is ~7 seconds but after adding an index as user_post_date the query time is less than a second.
