I misunderstood "numeric" to mean the NUMERIC type, but clearly they
mean any exact numeric type (which includes SMALLINT, INTEGER and
BIGINT).
Integers will now use the smallest type which makes casting up to
super-types much more straight forward.
Also, SQL tests will not stop on the first failure making it much easier
to cleanup multiple failing tests.
