Last month I installed the windows version of 8.0 RC1. The installation
installed postgresql as a service with user “postgres”, and an associated
password. “postgres” is a service user, not a standard user.
Yesterday, I uninstalled 8.0 RC1 and then installed 8.0 RC3. That worked,
once I realized that the “postgres” service user was never deleted, and
that I could only install RC3 if I remembered the password from RC1. I guess
I could also use a different name for the service user.
It seems that I may be able to change the password for the postgres service
user IF postgres is still registered as a service (before I uninstall). But, if I have
already uninstalled postgres, can I still change the password of delete the user?
