I think there is a bigger question here, why was auto table creation with first insert "Deprecated" at all? This to me just seems like change cause someone could change it that has no usefull purpose or is there some great purpose this serves? Same with creation of an already existing file, why did that need to become a noisy warning/error? -- Rod Grimes rgrimes@freebsd.org
