Hi Haogangmao, Ayush
Thank you for reporting the bug.
I verified this, and yes, this is the same crash as
https://www.postgresql.org/message-id/19382-4c2060ffee72759b%40postgresql.org
that Ayush mentioned.
I am actively working on that bug, fixed most of the cases. I am exploring
some corner cases that can reproduce the crash and fixing those too.
Regards,
