That would be a useful distinction, but I'm not sure how easily our
code can make it.

I'm not convinced that these cases belong in any of the standard's
classes.  IMO the standard is only standardizing application-visible
error cases, which these are not.  In particular I think class 2D is
not appropriate, since AFAICS the standard means that to pertain to
incorrect issuance of a COMMIT or ROLLBACK command.
