This infrastructure has been chosen because curl requires to be able
to use multiple types of libraries at run-time, right? I don't think
we need to get down to that for Postgres and keep things so as we are
only able to use one TLS library at the same time, the one compiled
with. This makes the protocol simpler. But perhaps I just lack
ambition and vision.
