The bit you call out above is for single row mode. Binary mode is a slippery slope, with or without the proposed callback. Let's remember that one of the biggest, often overlooked, gains when using an ORM is that it abstracts all this mess away. The goal here is to prevent all the ORM/framework folks from having to implement protocol. Otherwise they get to wait on libpq to copy from the socket to the PGconn buffer to the PGresult structure to their buffers. The callback keeps the slowest guy on the team...on the bench.
