There was a problem hiding this comment.
I decided to be a bit more verbose here (e.g. the shouldReturn use above unfortunately squishes the info about failed tests to a single line of code and single test name, this allows better debugging).
I can minify the getResult cascade code to a single zipWithM if required.

Hello,
essentially this is exposing the other function from the two here https://www.postgresql.org/docs/current/libpq-single-row-mode.html , which enable row streaming for looong queries.
The PR is quite straightforward so I'm not sure if much commentary is needed. I hope the C type mapping is OK. The wider context is that we'd really like to have it for continuing the work on valderman/selda#200 .
Thanks!
