У меня есть приложение Django и база данных Postgres, развернутая и докеризованная.Это мой docker-compose.yml
version: '3'
services:
web:
build: .
container_name: web
command: python manage.py migrate
command: python manage.py runserver 0.0.0.0:8000
volumes:
- ./src:/src
ports:
- "8000:8000"
depends_on:

postgres:
image: postgres:latest
container_name: postgres
environment:
POSTGRES_USER: my_user
POSTGRES_PASSWORD: my_secret_pass!
POSTGRES_DB: my_db
ports:
- "5432:5432"
Все отлично работает, я могу создавать, обновлять или удалять объекты любого из моих 10 приложений, однако, когда я пытаюсь удалить объект класса Story, что является следующим, это терпит неудачу:
class Story(models.Model):
title = models.CharField(max_length=255)
slug = models.SlugField(max_length=255)
author = models.ForeignKey(User, on_delete=models.CASCADE)
description = models.TextField(blank=True, null=True)
image = models.ImageField(upload_to="stories", null=True, blank=True)
Есть также несколько других классов, имеющих ForeignKey to Story, таких как Like, View или Comment.
Моя проблемачто я получаю операционную ошибку всякий раз, когда я пытаюсь удалить историю.Забавно, что я могу создавать или обновлять столько историй, сколько захочу, но не удалять их.
Когда я пытаюсь удалить любую историю, я получаю следующее исключение:
OperationalError: FATAL: the database system is in recovery mode
Если я посмотрю на выполненные запросы, я не увижу ничего плохого:
DELETE FROM "votes_like" WHERE "votes_like"."story_id" IN (91)
DELETE FROM "comments_comment" WHERE "comments_comment"."story_id" IN (91)
DELETE FROM "stories_story" WHERE "stories_story"."id" IN (91)
А потом:
OperationalError: server closed the connection unexpectedly
This probably means the server terminated abnormally before or while processing the request.
server process was terminated by signal 11: Segmentation fault
И историю, комментарии, мнения или лайки, которые у нее были,остается как обычно.
Я не испытываю такого поведения в localhost при той же настройке dockerized.
Я также пытался удалить строку, используя raw SQL в консоли, но это нене работает, соединение закрывается.

Есть подсказки?Я пытался решить эту проблему в течение нескольких дней, но понятия не имел, что делать дальше.
