Hello What I know no body is working on SQL/OLB ISO/IEC 9075-10 now. I proposed a 3 years ago a support of methods, but without success. This propose was rejected. There isn't a real interest to implement it from commiters. And I have to say - users doesn't request it too. And there are a few issues with compatibility. That's all what I know.
