This option is useful to do a rewind with the server configuration file (aka postgresql.conf) located outside the data directory, which is something that some Linux distributions and some HA tools like to rely on. As a result, this can simplify the logic around a rewind by avoiding the copy of such files before running pg_rewind. This option affects pg_rewind when it internally starts the target cluster with some "postgres" commands, adding -c config_file=FILE to the command strings generated, when: - retrieving a restore_command using a "postgres -C" command for -c/--restore-target-wal. - forcing crash recovery once to get the cluster into a clean shutdown state.
