Bug reference:      16680

PostgreSQL version: 10.5
Operating system:   Debian stretch 9.11. Core version: 4.9.0-11-amd64
Description:

Hello! Faced a problem regular server crashes.
There is no dependence on specific SQL queries.
Initially, the PG logs informed us about the crash on commits, as well as
other requests. It was not possible to identify patterns. Then we installed
autocommit on our application. Now there is no crash on commit, but it
happens on other random (as it seems to us) requests.
Server crashes are on average 10 times per day.
Also, crashes occur with the same symptoms on a server running PG 12.1.
The backtrace in the core dump is always repeated.
The volume of the database is 700 GB.
Attached are logs, backtrace and system information below.
