No, you're not. Because we don't do unix sockets on windows, for
obvious reasons.

You *would* get it on all RPM based installations, or DEB based
installations, on *unix*, unless the patch to initdb is done (which it
is now actually, just wasn't when I posted)

That said, it can easily be removed.

The idea being to let people know it's been deprecated, nothing else.
But sure, we can just remove the message - at elast for now, and maybe
add it $n releases down the road when people are expected to have
changed over.
