Chapter 3.42 - Adding fields
This is a Python command that runs a pyhton library (create_views.py) so it needs to be run either in the Python shell or in the command line of your QGIS computer:
./view/create_views.py --pg_service pg_qgep --srid 2056

The flag --pg_service calls the pg_service definition. So choose the pg_service definition of the database you want to run the script on.

I think the above notation works on Linux. I tried to apply it on Windows and get the following syntax error - maybe someone else has a hint for that?

I also guess that is needs a valid PUM installation on your system (see https://qgep.github.io/docs/admin-guide/db-update-pum/index.html#requirements)
