I retried database migration using another ... and the bug does not happen anymore.
The first time I use "Manual dump and reload" migration method from Archlinux wiki (https://wiki.archlinux.org/index.php/PostgreSQL#Upgrading_PostgreSQL):
# systemctl stop postgresql.service
# mv /var/lib/postgres/data /var/lib/postgres/olddata
# mkdir /var/lib/postgres/data
# chown postgres:postgres /var/lib/postgres/data
[postgres]$ initdb --locale $LANG -E UTF8 -D '/var/lib/postgres/data'
# /opt/pgsql-9.6/bin/pg_ctl -D /var/lib/postgres/olddata/ start
# /opt/pgsql-9.6/bin/pg_dumpall >> old_backup.sql
# /opt/pgsql-9.6/bin/pg_ctl -D /var/lib/postgres/olddata/ stop
# systemctl start postgresql.service
# psql -f old_backup.sql postgres
The second time I use the other way:
# systemctl stop postgresql.service
# mv /var/lib/postgres/data /var/lib/postgres/olddata
# mkdir /var/lib/postgres/data
# chown postgres:postgres /var/lib/postgres/data
[postgres]$ initdb --locale $LANG -E UTF8 -D '/var/lib/postgres/data'
[postgres]$ cd /tmp
[postgres]$ pg_upgrade -b /opt/pgsql-9.6/bin -B /usr/bin -d /var/lib/postgres/olddata -D /var/lib/postgres/data

I have kept the migration data (both of them). So I will compile PostgreSQL with debugging symbol to have a workable stacktrace.

Regards.

Vincent

Yes, I forgot to mention, that I also used quite recent version of gcc (GCC) 8.0.0 20170805 (experimental).
