Ok, this PR is starting to look much better. However, I'm a bit concerned about the lack of a molecule test. Is this something that can easily be tested in a Docker container? If not, can you test it locally on whatever platforms you have access to?

this has been tested as part of the project https://github.com/vitabaks/postgresql_cluster

I didn't do any molecule tests as part of this PR.

@vitabaks Ok, this PR looks good. :+1: Could you please run a quick test with the latest changes before I merge?

@vitabaks Great! Unfortunately some linter tasks are failing on our end. :disappointed: I'll investigate those this afternoon and try to come up with a fix.
