Bart, On the servers I have running the log file format does not change.
Also, arjun decreased the ammount of stuff spit out by QD in mid august
and very little should be printed by the query dispatcher at this point.
(even with Debug on).
If you are seeing things like "Notice: Querying (sql query follows)"
or "Notice: dbinit: sql(localhost::DBNAME) ..."
those are not actually from the query dispatcher and are instead being
printed because you have the postgres driver set to verbose.
(the messages have a different header for oracle but same idea there).
