I agree that the buffering change is not likely interesting, but
the fact that you can now control-C out of a psql "\c" command
is user-visible. People might have internalized the fact that
it didn't work, or created complicated workarounds.
The buffering change improved performance up to ~40% in some of the
benchmarks. The case it improves mostly is COPY of large rows and
streaming a base backup. That sounds user-visible enough to me to
warrant an entry imho.
