Databases are usually very customizable with varying data types and custom lengths.

It surprises me, as I try to look for the syntax to use `unsigned int` types that they are not available from neither PostgreSQL and MS SQL Server. MySQL and Oracle seem to.

This seems like a glaring omission on their part - the next best perfomant option being a long/bigint, (8 byte integer), but could be completely unneccessary! Does anyone know why they would choose to not include native unsigned int support?
