No. So you wind up with new parameters just getting defaults, and not specified or documented in the file. Couple of ways around this: - Put your parameters in a separate file that's included into postgresql.conf. - Generate a new db, diff its config against the old one to see what's new that you might want to change, and use it with the inclusion of your settings.
