We already have that: it's called the existing libpq API.
The only reason I can see for offering any new feature in this area is
to cater to apps that want to transform the data representation
on-the-fly, not merely dump it into an area that will be the functional
equivalent of a PGresult. So it really has to be a callback.

Why not? That would eliminate a number of problems.
