Improve readme regarding usage of other databases e.g. PostgreSQL

The support of PostgreSQL as alternative to MySQL seems important to me.

Nothing stops you from using a PostgreSQL database. There is an official docker image you can use.

You don't even have to use a docker container. You could also run a "classic" installation of PostegreSQL on the host or another machine.

You just have to insert the connection info in the Nextcloud setup wizard.

The Dockerfile already provides the required extensions to use MySQL/MariaDB/PostgreSQL. As @SnowMB said, you only have to connect to a PGSQL instance during the Nextcloud setup wizard.

These explanations should be more detailed in the README.

Alright, thanks for the insight, that's what I needed to know.

Indeed, this should be in the readme, so people like me don't need to ask 😉

I changed the title to make this issue about documenting the database connection better.
