After crafting of a "proper" config.yml [1] because otherwise it complains [2].
It complains about missing implementations [3] [4].
This currently prevents migration with the proper tooling as per documentation [5]
[1] config.yml:
```
swhworker@scrubber0:~$ cat config.yml
---
scrubber:
cls: postgresql
db: host=<host> port=<port> dbname=swh-scrubber user=swh-scrubber password=<password>
```
[2]
```
swhworker@scrubber0:~$ swh db --config-file /etc/softwareheritage/scrubber/postgres.yml upgrade scrubber --to-version=2
Usage: swh db upgrade [OPTIONS] MODULE
Error: Invalid value: Configuration cls must be set to 'postgresql' for this command.
```

```
swhworker@scrubber0:~$ swh db --config-file config.yml version scrubber
