It is of course possible to obtain the current values contained by the settings
listed on that page with e.g.:

     SHOW config_file

or

     SELECT setting FROM pg_settings WHERE name = 'config_file'

Server has to be running, of course.

The various ways of getting current parameter values are documented on the previous
manual page here:

     https://www.postgresql.org/docs/10/static/config-setting.html#config-setting-sql-command-interaction
