Aside from the security questions, please consider that this feature should
work similarly to the current implementation of the pg_file_settings view,
namely it tells you about what is *currently* in the on-disk files, not
necessarily what is the active setting in the postmaster's memory.
A backend could not be entirely sure about the postmaster's state anyway;
and even if it could be, one of the major applications for features like
this is testing manual changes to the files before you SIGHUP the
postmaster. So re-reading the files on each usage is a Good Thing, IMO,
even if it sounds inefficient.

Yes, that seems rather random to me too.
