I have had the same problems.  
Finally I inserted the following as a workaround

```plaintext
   if Rails.env.development?
      username = "discourse"
      password = "discourse"
      config["host"] = "localhost"
      config["port"] = 5432
      config["database"] = "discourse_development"
    end

```

before

```plaintext
  DatabaseConfiguration.new(

```

into `/lib/backup_restore.rb`.

I also had to set the password for user `discourse` via

```plaintext
d/psql -c "ALTER USER discourse WITH PASSWORD 'discourse';"

```

There might be nicer ways to achieve this.
