If I'm reading my draft copy of the SQL:2003 standard, SQL only
specifies SMALLINT, INTEGER, and BIGINT integer types. There are no
unsigned integer types in the standard. While PostgreSQL does have
datatypes which extend the SQL standard, either no one has felt the
need for an unsigned data type or it has not been accepted by core.
You could check the mailing list archives for details if you wish.
