Postgres Docker container not shutting down from vscode Rebuild command [closed]

I have a very simple Docker project setup with a vscode devcontainer.

There are two Docker containers, dev and db

This works! I open the project in the devcontainer and everything works fine, until i have to rebuild the container: When I do the vscode devcontainers: Reload container command the dev service container is closing and deleted as expected. However, the db service container is not. The restart policy even set to "no", it just refuses to shut down at all, causing a new error because the new rebuilder db container wants to use the port that is still in use on the old container.

It looks like the default setting in devcontainer.json "shutdownAction": "stopCompose" is completely ignored by Docker or by the db container itself. (i tried to explicitly set that setting in the devcontainer.json as well without success).

Here are the relevant files:

docker-compose.yml

  dev: 
    container_name: trading-platform-dev
    build:

    tty: true
    stdin_open: true
