klazaj opened a new issue #8811: Connection failed/refused when connecting to local PostgreSQL Database URL: https://github.com/apache/incubator-superset/issues/8811 I'm trying to connect Superset with my local PostreSQL database via this URI: `postgresql://superset_user:password@localhost/superset ` When I test the connection, I get the following error: `ERROR: {"error": "Connection failed!\n\nThe error message returned was:\n(psycopg2.OperationalError) could not connect to server: Connection refused\n\tIs the server running on host \"localhost\" (127.0.0.1) and accepting\n\tTCP/IP connections on port 5432?\ncould not connect to server: Cannot assign requested address\n\tIs the server running on host \"localhost\" (::1) and accepting\n\tTCP/IP connections on port 5432?\n\n(Background on this error at: http://sqlalche.me/e/e3q8)", "stacktrace": "Traceback (most recent call last):\n File \"/usr/local/lib/python3.6/site-packages/sqlalchemy/engine/base.py\", line 2265, in _wrap_pool_connect\n return fn()\n File \"/usr/local/lib/python3.6/site-packages/sqlalchemy/pool/base.py\", line 303, in unique_connection\n return _ConnectionFairy._checkout(self)\n File \"/usr/local/lib/python3.6/site-packages/sqlalchemy/pool/base.py\", line 760, in _checkout\n fairy = _ConnectionRecord.checkout(pool)\n File \"/usr/local/lib/python3.6/site-packages/sqlalchemy/pool/base.py\", line 492, in checkout\n rec = pool._do_get()\n File \"/usr/local/lib/python3.6/site-packages/sqlalchemy/pool/impl.py\", line 238, in _do_get\n return self._create_connection()\n File \"/usr/local/lib/python3.6/site-packages/sqlalchemy/pool/base.py\", line 308, in _create_connection\n return _ConnectionRecord(self)\n File \"/usr/local/lib/python3.6/site-packages/sqlalchemy/pool/base.py\", line 437, in __init__\n self.__connect(first_connect_check=True)\n File \"/usr/local/lib/python3.6/site-packages/sqlalchemy/pool/base.py\", line 639, in __connect\n connection = pool._invoke_creator(self)\n File \"/usr/local/lib/python3.6/site-packages/sqlalchemy/engine/strategies.py\", line 114, in ...` I tried all the variations of `host:port` such as 127.0.0.1:5432, but the connection still fails. The `\conninfo` output displays `You are connected to database "superset" as user "superset_user" via socket in "/var/run/postgresql" at port "5432".`, so this should theoretically work.
