It's this line: https://github.com/zalando/postgres-operator/blob/master/docker/logical-backup/dump.sh#L48

I wonder why that variable is there. It results in "my-bucket-url" if it's not set, which seems undesirable.

EDIT seems like setting it to "" will result in a no name folder, also not great.
