info schema : cardinal number domain

When creating a table with a bit type
of length less than 4, then any selection
to the information.schema.columns table
that hits that row gives the following error:

drop table infoschema_bit;
create table infoschema_bit (
bitcol bit(3)
);
select * from columns;

-- ERROR: value for domain cardinal_number violates check constraint "cardinal_number_domain_check"

There may be other places where this hits.
I ran into it creating an "alltypes" table for
an example and just grabbed the bit(3) from the
documentation on the bit type.

This is relatively low priority as I suspect
few people use both the information schema AND
small bit types right now.
