Yeah, if we're going to have this at all, some form of GUC control over
it seems necessary.  I'm still disturbed by the verbosity of the
proposed output though.  Couldn't we collapse the information into a
single log entry per checkpoint cycle?  Perhaps that would be sufficient
to just let the log_checkpoints setting be used as-is.
