These are MTA configuration variables.

The man-pages in question have nothing to do with Postfix configuration
variables.
The correct way to not duplicate the MTA name into main.cf, while
getting the desired domain appended to the host's short-name, if
the default "localdomain" is not appropriate is to add:
mydomain = example.com
to the top of main.cf.

It is deliberately done right to ensure reliability, stability and
correct operation of non-networked hosts. Please stop. And close the
Debian bug-report please, if you persist too much, someone who understands
Postfix poorly may decide to fix the "bug" for the Debian community.
Yes, this would not be quite as dramatic as the OpenSSL PRNG botch, but
it would still be a mistake, and cause needless pain and effort to undo.
