Looks OK on a quick look. I tried to verify that it is the exception that
bubbles up at the point in code I marked in my first email. If I didn't
completely misread the traceback that should be correct exception to catch.

Hope you can test this in a test cluster before going for production. I
guess the worst case for this change is that WAL uploads would start
failing if there is a typo or something somewhere..
