I kinda suspect it might be just a coincidence that it fails during that
particular test. What likely plays a role here is a checkpoint timing
(AFAICS that's the thing removing the file). On most systems the tests
complete before any checkpoint is triggered, hence no issue.
Maybe aggressively triggering checkpoints on the running cluter from
another session would do the trick ...
Now that I recall, another thing I forgot to mention on this thread is
that I patched guc.c to reduce the minimum of checkpoint_timeout to
1s.
But even with that change you haven't managed to reproduce the issue,
right? Or am I misunderstanding?
