Re: PROPOSAL FE/BE extension to handle IN/OUT parameters

Yeah, I think that might work if I understand it correctly.

Assuming I would be able to prepare, and bind all the parameters, and  
the OUT parameters
would be ignored.

FWIW, I proposed adding to the protocol, not modifying the existing  
messages, so it would be backward compatible and not break existing  
clients.
