I set up a local installation with docker [https://github.com/metabrainz/musicbrainz-docker] and like to connect the PostgreSQL-Server obviously running. I found some credentials in the file
But even the user musicbrainz mentioned there is not connected!
Ends up with
Connection to localhost:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections. [SQL State=08001]
Changing host from localhost to 127.0.0.1 doesn’t make it work neither. Can someone tell me how to connect to PostgreSQL please?
