It's funny that the two boolean arguments are always opposite.
They're essentially both saying "top level?".  I was also a bit
confused about who else would delete the file in between the check and
the attempt to open it with my proposal, considering this is code
running in the postmaster at startup, so I figured I must be missing
something and hadn't got around to figure out what and replying.
Thanks for fixing this.
