Yes, but what is currently missing is a protocol to the backend where a statement is prepared with placeholders and then executed (multiple times) with given values. Then there is no doubt what is a value, and what a part of the SQL. I think that this would be a wanted feature of the next protocol version. iirc the backend side part is currently beeing implemented.
