Nonnumeric Primary Keys

Hey, all I have a db in production that uses a whole lot of string values as primary keys. (It's Oracle, FWIW) Does DBIX::Class care what data type a primary key is? I *vaguely* remember hearing some sort of remark in the Catalyst master class Jon Rockway taught at YAPC that this is an issue, but I might have imagined it.

Thanks,
Karen
