Can't you do that today with a multi-command string submitted to

It's more annoying to to error handling on that, plus it still keeps the
blocking behaviour, just with larger blocks.
You can combine multi-command query strings with nonblocking mode,
without any change in libpq itself.
In fact that's exactly what the libpqxx "pipeline" class does. So if
you're working in C++, you already have this feature at your disposal.
Also I would ask for opposite feature: "multiple rows in flight".
That means that when server is sending big resultset,
the app can process it row-by-row (or by 10 rows)
without stopping the stream and re-requesting.
Cursors.
