By cviebrock:

I don't use Postgres, so I just assumed it did have one. A bit of googling seems to suggest it doesn't. Further searching indicates the neither does SQL Server, and SQLite (I think) just ignores it. Can you tell who's only used MySQL for their projects? ;)

My suggestion would be to either:

1. Revert this patch and be done with unsigned ints entirely (better portability, I suppose), or
2. Change the unsigned() method in grammar.php to return an empty string, and move the unsigned() method above into mysql.php (to overload the base method).

Thoughts?
