Yeah, that's annoying but there's no very good way to work around it.
Fortunately, the logger doesn't die very often. All of the use-cases
I've thought of for wanting to capture stderr output for it amount to
debugging of some form or other, so it's probably good enough for that
to only work in the first logger incarnation after database start ---
but Reinhard is proposing to make it not work at all, and that I don't
like.
