Changing PG_AUTOCONF_FILENAME even by developer would
lead to loss of useful configuration settings (if any done by user via
ALTER SYSTEM) and on starting server user will see some
log message indicating that it has skipped processing configuration
file. I think the impact of changing this define is not so severe that
someone has to do initdb, however it's non-ignorable impact.
The file header of pg_config_manual.h seems to suggest that this
file contains such parameters.
