Yep, the standby registration information should be accessible and
changable while the server is not running. So using only system
catalog is not an answer.
My patch has implemented standbys.conf which was proposed before.
This format is the almost same as the pg_hba.conf. Is this
machine-editable, you think? If not, we should the format to
something like xml?
