Tests need pytest-asyncio installed.

Tests need a local postgresql instance running, this can best be done using
```sh
docker run --rm --name some-postgres -e POSTGRES_USER=foo -e POSTGRES_PASSWORD=bar -d -p 5432:5432 postgres
```

The tests use the following credentials to establish a database connection.
