it feels i tried out everything, connecting to the postgres database via pycharm.
if i type in my command line:
psql 'dbname=mydatabase user=elsa' it works perfectly and i'm connected to my database. I have no password.
I am sure i use port 5432 as i did (https://stackoverflow.com/questions/5598517/find-the-host-name-and-port-using-psql-commands), which is the default port.
i tried to use: https://jdbc.postgresql.org/documentation/80/connect.html to get directly a url to connect, i tried:
I am asked to privide my username and password (elsa, none) always getting the same error massage:
The specified user/password combination is rejected:  The server requested password-based authentication, but no password was provided.
thanks in advance :)
