That seems like just a kluge, as you'd typically want query-by-query
control, and a GUC setting isn't convenient for that.

It's entirely possible that the current protocol definition is Good
Enough, assuming that client-library designers are aware of the
implications of using named vs unnamed statements (which I bet not
all of 'em are).  You *can* have either behavior today, so far as
client-issued queries go.  The area that seems to need work more
drastically is controlling what happens with queries inside plpgsql.
