Bug in DatabaseMetaData.getColumns() with columns based on domains

Hi,

consider the following table and domain:

CREATE DOMAIN salary_domain AS numeric(12,2) NOT NULL CHECK (value > 0);
CREATE TABLE employee (id integer not null, salary salary_domain);

DatabaseMetaData.getColumns(null, "public", "employee", "%");

returns "YES" for the column IS_NULLABLE in the ResultSet whereas it should flag that column as not nullable.

Regards
Thomas
