remove postgres server from local machine I know this is a real beginner question. But nevertheless I'm really confused:/
I wanted to have a clean installation of postgres on my ubuntu laptop. So I tried to delete everything related to postgres.
However, when I start running the PgAdmin, I see this under the servers:

I don't even remember when I created this robin_test-server. But now I fail to remove, connect or find any information about it. Anybody might have an idea on what to do in this situation? Any help is super appreciated:)
PgAdmin stores preferences and a list of servers in the .pgadmin directory in your HOME directory.
To reset it to a pristine state, you may delete this directory, when the application is not running.
