PostgreSQL installation fails.

The PostgreSQL installation fails. Take a look at the following patch that has it working on my development system.

Also attached is the patch for review. Unsigned is explicit on PostgreSQL if you are looking to do a constrain as such I would recommend the CHECK syntax in PostgreSQL.
