IIRC we do have a GUC property that hides the value from non-superusers,
so we could easily have a GUC that is equivalent to the proposed
pg_primary_conninfo function. Of course this does nothing for my
objections to the function. Also, I'm not sure how we'd deal with the
state-dependency aspect of it (ie, value changes once you exit recovery
mode).
