Comment (by Rodrigo Vieira):
I did some tests on SQL Fiddle ([https://sqlfiddle.com/mariadb/online-
compiler?id=6af2699e-0a91-403e-a758-0a331294916a here]) for MariaDB, and
it also optimizes the use of covering index, so it seems that we can
consider that all databases supported by Django would benefit from this
optimization.
