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

```
2022-12-23 08:50:20.175 UTC [34653][postmaster] LOG: server process (PID 37171) was terminated by signal 6: Abort trap
2022-12-23 08:50:20.175 UTC [34653][postmaster] DETAIL: Failed process was running: VACUUM FREEZE tab_freeze;
2022-12-23 08:50:20.175 UTC [34653][postmaster] LOG: terminating any other active server processes
```

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].
