I'll check later - I am assuming that this is the logfile it is
complaining about.

When I was watching it in the Task Manager, it was observable that the
postmaster exited before some of the other backend processes, by up to a
second or two. I suspect a sleep would cure most of the problem, but it
seems a bit arbitrary - is there a more robust way on Windows to check
that needed files are unlocked?
