isready for testing. I'd want to get some specific tests against the common monitoring goals of tools like
check_postgresand the Munin plug-in to see which implementation makes more sense for them as input on that.
ISTM this should be driven by what data we actually expose. If we're willing to expose actual information for idle,
idle_transactionand waiting for backends that you don't have permission to see the query for, then we should expose the
actualinformation (I personally think this would be useful).
OTOH, if we are not willing to expose that information, then we should certainly set those fields to null instead of
somedefault value.
