Как отследить падение postgresql

Postgres запущен на удаленном linux серевере. Бэк Spring Boot обращается к этой БД. Бэк пока крутится в докере и обращается к postgres развернутой на сервере с публичным доступом по паролю. База периодически падает, не понимаю как отследить из-за чего она падает. Пробовал добавлять логирование в бэк и постгрес.

После рестарта postgres всё снова работает.

Вот такие методы Rest API выполняются (CRUD операции с базой). Ничего не падает.

p.s. картинки в базе не храню, только информацию о них.

Вопрос: Как отследить причину падения базы? Она выключается как будто в случайный момент.
