I had in mind to just "git revert" the patch when we're done with it.
There might be some parts we want to keep (for instance, I'm thinking of
logging "postmaster is done" after we've unlinked the pidfile, which might
be useful permanently).  But I plan to err on the side of noisiness for
the moment, rather than make something I think has long-term value.
