Hi, the msi installer for Windows automatically creates a user 'postgres' if CREATESERVICEUSER=1. Is it possible to do the following: 1) don't create the user, if it already exists, and continue with installation, instead of showing the error message 'user postgres already exists'. 2) during uninstallation, delete the user 'postgres' automatically, when it has been created during installation.
