That still has problems.

Another approach would be to restrict the existing datatype NUMERIC to
508 digits, but introduce a new datatype of LONGNUM which allows
arbitrary length numerics for those that *do* care. It might be more
beneficial in the longer run to separate the use cases so we can further
tune them (not sure how just yet...)
