This is one of the reasons why an external config file isn't as great
an idea as some people think.
I wonder whether we shouldn't simply remove the ability for
postgresql.conf to exist outside the data directory (which would be
mechanized by removing the ability to set data_directory to something
other than the place where the config file is found). People who prefer
to keep their config somewhere else can reduce the in-the-directory file
to just "include /some/other/file". But otherwise, this would get rid
of a confusing and completely unnecessary inconsistency between
different installations.
