I'm inclined to think there would be value to a pg_ping utility to
support automated monitoring by unprivileged users on other boxes.
That both suggests libpq as the location, and one or two additional
pieces of information. An indication of "in archive recovery" versus
production or shutdown, for example, might be useful. I'm not sure
what else might make sense.

I'm a little lost on that. Would it cause any problems for pg_ctl,
or just be more than it would need if it's only implemented there?
