Yeah that could be a possibility, but I think that will break the existing
command('s) as this is the common infrastructure used for SHOW ..
commands as well which displays the guc value that is used by
current session rather than the value in postgresql.conf.
I don't know how appealing it would be to others, but a new view
like pg_file_settings which would display the settings in file could
be meaningful for your need.
Another way is user can do pg_reload_conf() to see the latest
values (excluding values for server startup time parameters).
