Just from curious may I ask in which direction this will go, and how this will 
affect performance of text and binary format?

Actually I started to make smaller improvements, and I think about one big to 
encode text (when client and server encoding are different) directly to 
StringInfo, without intermediate buffer.

Thanks in advice
Radek
