Hello,
Thanks to Kunal Mehta, CI now supports running MediaWiki tests using the Postgres database! It has been requested since 2012 ( T39602 ) and finally came to fruition.
Unsurprisingly, a few tests are failing and require some assistance. Anyone is welcome to help on that front. See T195807 for a list.
Please celebrate Kunal!
