#32878 was closed with "MySQL is the suggested backend so our akonadi package will use it (and then require it)". #33400 #52200 #62243 were all closed as they appeared, though #62243 achieved something else.

* #32878 was 8 years ago. KDE TechBase states that MySQL and PostgreSQL are both supported without preference for a particular database. (https://techbase.kde.org/KDE_PIM/Akonadi#Which_DBMS_does_Akonadi_use.3F)
* The Wiki has a hacky note about installation without mariadb via --assume-installed. (https://wiki.archlinux.org/index.php/KDE#Akonadi)
* Packages like nextcloud have DBMS backends as optdepends. (https://www.archlinux.org/packages/community/any/nextcloud/)

It would be good to have both mariadb and postgresql as optdepends to akonadi instead of the way it currently is. Going the phonon way and introducing a akonadi-backend virtual package, as suggested in #32878, seemed a good solution as well.

Unlike the other mentioned software, Akonadi doesn't just detect available DB backends and uses what's available, Akonadi uses the DB backend that was set at compile time (which defaults to MySQL).
This means that if you use the default, then you don't need to configure anything, but to use a different DB backend you will need to edit ~/.config/akonadi/akonadiserverrc before using akonadi. Even if mariadb was not a dependency of akonadi, you would still need to edit akonadiserverrc.

Wouldn't it then be possible to mark both as optdepends and edit the wiki to say you need to install a DB backend, and if the DB backend of your choosing isn't MariaDB, that then you have to edit the config?

Nextcloud has a DB setup section on the wiki, which is more complicated than just editing a single variable as would be the case with akonadi

I was going to propose patching upstream or creating new packages. But this is a simpler and better solution to the problem. Thanks.

Installing a cloud server isn't really comparable to using a mail client, which is expected to work out of the box.
