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.

Regards

Pavel Stehule
