IIRC pgFouine shows exact percentage of query by type; this new GUC implies we
can not rely on it anymore. Also, you could skip us from logging long (and
bad) running queries. Another statistics data in pgFouine will suffer from the
same problem. I see your point in reducing amount of log data but I think it
will limit the tool usability (you can always start/stop statement collection
at runtime).
