Postgres 11.5.1 failed installation

Hello, I tried to upgrade the postgres’version but something goes wrong with the privileges may be. I attach a log about the problem.

Also I saw on the stackoverflow the same problem but with 10.10 version -> https://stackoverflow.com/questions/57480005/postgres-failed-to-install

Thank you for any suggestions to resolve it or do we need to wait for another installation assembly.

With regards,

Petar Masev
