mysql-native: API Refresh RC

ResultSet querySet(Connection conn, string sql, 
ColumnSpecialization[] csa = null)

Could you explain last parameter?

`ColumnSpecialization[] csa = null`. I can't understand how to 
use it.

Could you give me your skype?

Also I think it's better to remove old deprecated methods at all, 
because it's add only mess.
