Upgrading PostgreSQL to a new major version - Teslamate

Create a backup
Stop all TeslaMate containers
bash
```
docker compose down
```
Delete the database volume. Be careful, this will delete all your previously recorded data! Make sure that your backup can be restored before you start.
bash
```
docker volume rm "$(basename "$PWD")_teslamate-db"
```

Change the postgres version and ensure your volume mount is configured correctly in docker-compose.yml and start the container

yml

database:
  image: postgres:18-trixie
  ...
  volumes:
    - teslamate-db:/var/lib/postgresql

bash

docker compose up -d database
