Sorry, I meant $1 in place of the ?. No special parsing needed, psql can 
send the query to the server as is, with the parameters that are given 
by this new mechanism.

I'm not too happy with the COPY approach, although I won't object is one 
of the other committers feel more comfortable with it. However, we don't 
seem to be making progress here, so I'm going to mark this as Returned 
with Feedback. I don't feel good about that either, because I don't 
actually have any great suggestions on how to move this forward. Which 
is a pity because this is a genuine problem for users.
