Git clone password problem

[ianb]

This probably does not have anything to do with the SSH key or the Raspberry Pi, its probably a permissions issue that is common with getting the App Server to start, with most defaults for how to start a PostGreSQL database engine.

This link will not have your answer but it describes the same problem on a different system, there is something wrong with your postgres permissions probably:

[App Server] Failed to start built-in Postgres database

I faced a similar issue. Postgre logs below Execution of PostgreSQL by a user with administrative permissions is not permitted. The server must be started under an unprivileged user ID to prevent possible system security compromises. See the documentation for more information on how to properly start the server. What worked for me was run my IDE in ‘non-administrator’ mode. I imagine fix will be the same for when running power shell and command prompt. Hope it helps.

So if you can figure out how to get postgres to run it should unpack the rest of the app server with minimal issues.
