How to COMPLETELY delete psotgreSQL?

[royalroy123]

Hi,

I got a new computer and tried to install HM. Unfortunately, something went wrong and I reinstalled postgresql and HM, but I cannot install postgresql now as stated in the installation guide, altough I unistalled it. It always says that a database/account already exists.
What do I have to do to install postgresql as it would be the very first time.

Thanks a lot!

Kind regards
