I have investigated the failure and it seemed that it has been caused by VACUUM 
FREEZE.
Followings were copied from the server log.

```

37171) was terminated by signal 6: Abort trap

```

Same error has been raised in other threads [1], so we have concluded that this 
is not related with the patch.
The report was raised in another thread [2].
