I'm not sure what failure mode you're imagining, but the postmaster has
already verified that all the children that are supposed to be connected
to shared memory are dead before it attempts to recreate shared memory.
So the above sounds completely bogus.

I'm still suspicious of the syslogger holding onto an inherited handle
to the shared-memory file, though that theory would seem to mean that
crash recovery would never work at all on Windows if the syslogger
were enabled. But maybe there is some additional gating factor needed
to cause the problem to manifest.
