Although I thought its fragile-ness was acceptable to avoid making the patch too complex, I agree with you. The third patch is attached, modifying mb routines so that they can receive conversion procedures as FmgrInof * and save the function pointer in CopyState. I tested it with encoding option and could not see performance slowdown. Regards, -- Hitoshi Harada
