After upgrade to 5.0 (with docker-compose): failed to connect to server

Everything was working fine and we upgraded form v3 to v4 to v5 with the docker-compose upgrade command, and the redash UI is loading fine, but cannot execute any query.

The UI displays an error: Error running query: (psycopg2.OperationalError) could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

And the docker-compose logs shows the following:

redash-worker | [2018-10-15 10:40:30,331][PID:46][INFO][Worker-13] waiting tracker 14a3e1bd6ffb17fda50f3ef34071f77f finished

Any ideas? Thank you so much

Just a typo here, it’s correct in the docker-compose file. I have REDASH_DATABASE_URL: "postgresql://postgres@postgres/postgres" in the server container and REDASH_DATABASE_URL: "postgresql://postgres@postgres/postgres" in the worker container, and the result of the docker-compose up -d command is: OperationalError: (psycopg2.OperationalError) fe_sendauth: no password supplied
