Ошибка при восстановлении 1C базы PostgreSQL

Здравствуйте.

При восстановлении базы из бэкапа утилитой pg_restore выдает два предупреждения (ранее такого не было). Ниже.
База восстанавливается, и работает.
Как это можно исправить, и насколько это критичные ошибки?

Ранее было обновление платформа 8.3 и PostgreSQL12.5.
