18% of people running Nextcloud don't know what database they are using

If you’re running it in a prebuilt container, as long as it works it shouldn’t matter.

Of course, when your database gets corrupted after Nextcloud updates because you had an app running that isn’t supported in the new version, it will suddenly matter a lot.

Will Nextcloud run apps not marked as compatible with that version?
You can specify the behavior in a few places, gui, occ command, config.php. By default no, but if you have an app you want to force in regardless of the version compatibility you can make it so

[Help] What is app_install_overwrite for?

There are 2 apps in the app_install_override list in my NextcloudPi configuration. Every time when they get updated automatically they are disabled and I have to enable them manually again. What is this list for?
