Postgres over Sqlite

[MayMeow]

A few commits back I switched to using SQLite database because application development with it is much easier (you don't need any additional server) Eventually, however, I will go back to Postgres, mainly for the following reason:

The application for production environment is built on CI and the user is set to www-data which causes a problem with access rights to the database file.

I find that it is probably easier to add another database service to the docker-compose subfile than to create a new folder for database and set access rights on each installation.

The lines above were against using sqlite

The reason for using sqlite is that I don't plan to use this application for a large number of visitors on a regular basis (my blog has about 100 visitors a month). Also the database backup is easier.
