I must admit every time I see this wording, it strikes me as very specific
and potentially confusing given the alternative files the parameter could be
placed in.
I think it would be clearer for anyone not familiar with the configuration file
system to change occurrences of this wording to something like:
This parameter can only be set in the <link
linkend="config-setting-configuration-file">configuration file</link>
which would link to:
https://www.postgresql.org/docs/current/config-setting.html#CONFIG-SETTING-CONFIGURATION-FILE
which provides more information. Though on that page it seems like it would be
also sensible to bundle the section about include directives in the
configuration
file (19.1.5) together with the section about the configuration itself (19.1.2).
