What are you fixing here? sudo sudo … is supposed to work just fine.

sudo sudo

ok. I didnt try it. As I said in another comment I personally use sudo -u postgres and I thought this sudo sudo meant to be the same as https://github.com/os-autoinst/openQA/pull/6665/files#diff-4d6d1050121df87969e32770abd50500a1fbda9f136db4fbb374fe05a236f2c2R393

The sudo sudo -u postgres command is useful if you're not already root. If you just run sudo -u postgres as your normal user you might be prompted for the password of the postgres user

@d3flex Given the reasoning from the review thread, I assume it's clear by now that this is not a typo.

For what it's worth I think it's good that you review the docs and consider fixing mistakes along the way.
