It does more, per the pg_ctl man page:

    postmaster.opts

        If this file exists in the data directory, pg_ctl (in restart
        mode) will pass the contents of the file as options to postgres,
        unless overridden by the -o option. The contents of this file are
        also displayed in status mode.

It seems totally reasonable for "pg_ctl restart" to re-apply those
switches.  If you don't want that, don't use "restart", but stop
and start.

Or you could just remove the file.
