Some initial hacking, about 2 coffees' worth:
https://github.com/macdice/postgres/commits/oauth-kqueue

This compiles on FreeBSD and macOS, but I didn't have time to figure
out all your Python testing magic so I don't know if it works yet and
it's still red on CI... one thing I wondered about is the *altsock =
timerfd part which I couldn't do.

The situation on macOS is a little odd: the man page says EVFILT_TIMER
is not implemented. But clearly it is, we can read the source code as
I had to do to find out which unit of time it defaults to[1] (huh,
Apple's github repo for Darwin appears to have been archived recently
-- no more source code updates? that'd be a shame!), and it works
exactly as expected in simple programs. So I would just assume it
works until we see evidence otherwise. (We already use a couple of
other things on macOS more or less by accident because configure finds
them, where they are undocumented or undeclared.)
