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.
