Good point. It'd be worthwhile to have some way of extracting such
information from the clients as well.

Is that sufficient? The clients probably are not affected by quite as
many config options as the server, but they still have a nontrivial
list. (Multibyte, SSL, Kerberos come to mind at once.) I'd not like
to see us assume that a one-line output format will do the job.
A way to interrogate the libpq being used by psql might be good too.
