Hi,
Over the past few months, I've been working with LFaraone, Faidon, and Moritz on updating the super old 1.19.x Debian package of MediaWiki to use a more modern version (currently 1.25.x) and just generally improve the quality of it. (Yes, it uses MySQL by default, not postgres!)
It's currently waiting in the "new" queue[1], but if you'd like to test it out, I've uploaded the debs at [2]. If you find any bugs or have feature requests, you can let me know or file a request in the MediaWiki-Debian[3] Phabricator project. The debian/ files used to create the package can be found in Gerrit in the mediawiki/debian repository[4].
