This question has been touched on before, but I guess it's time to face it fair and square: is it reasonable for an SQL implementation to add implementation-specific columns to an information_schema view? One could certainly argue that the entire point of information_schema is to be *standard*, not more, not less. OTOH I do not know if adding an extra column is likely to break anyone's application. Comments?
Well, I suppose it reduces application portability if anyone starts relying on it.
We're advertising to do pure ANSI, so we'd mislead people if we supplied non-standard columns.
