The important part of the postgres container, so backing up the data folder is enough. Starting a new container is cheap in your situation, the data is what is important.

The there no obvious reason for why the volume won't work, unless you delete the postgres-data folder accedentaly.

In summary, by inspecting the compose file, things are normal and safe.
