title: Problem running post-install step. Installation may not complete correctly The database cluster initialisation failed
body: <p>Installing PostgreSQL v12.3 on Windows 10 with Windows x86-64 installer. I can't find a solution anywhere. Installer allows me to click ok and continue installation. I even have access to all the apps that come with Postgres, including the pgAdmin4 app, but I the 'psql' command in my command line doesn't work.</p>
  
  <p>Anyone know how to resolve this?</p>
