Thanks. I tried to notify some affected wikis but surprisingly there is only one registered on WikiApiary: https://bucardo.org/wiki/Special:Version
With some very wide Google searches like 'postgresql "powered by mediawiki"', I found a few more: * https://www.alteeve.com/w/Special:Version * https://forge.fiware.org/plugins/mediawiki/wiki/fiware/index.php/Special:Ver... * https://wiki.mageia.org/en/Special:Version (we know them, they're working on upgrades and a Translate installation) * http://www.pgpool.net/mediawiki/index.php/Special:Version * https://wiki.koha-community.org/wiki/Special:Version * http://postgres.cz/wiki/Speci%C3%A1ln%C3%AD:Verze * https://wiki.mahara.org/wiki/Special:Version
I'll notify these as well if nobody beats me at it, but I assume there are more; any idea how to reach them?
