Beofre i review that further:
You missed some coding standards we keep around here, but overall it dose not look to bad. First look in the latest merged Scripts for exampled. Second: We habe helper functions in tools.func to set up Node.js and Postgress.
3. We dont do git pulls, just downloads of releases. Ther also exists a helper function in tools.func.

Also please remove any comments, also you can then remove the jq check in the update part.
You can ping me when you did the changes, then i will have a deeper look into this pr.
