Yes, that's indeed a bit inconsistent with the other parameters able to
use boolean-like parameters, like sslcompression or sslmode (deprecated
in favor requiressl), still those two ones are frontend-only
parameters, so they are just able to use "1" or "0". Replication is
part of the startup packet which uses parse_bool() so valid values can
be true, false, yes, no, on, off, 1 or 0. And it is even possible to
use upper-case characters. So why not documenting all that precisely

Indeed, this term is pretty spread across the documentation as well.
I have taken into account this feedback, and created the new version
attached, for a v2.
