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?
