我正在尝试从Redash连接到本地Postgres。（都来自redash.io和http://0.0.0.0:5000/），但无法连接到它。我可以连接本地主机的其他工具，但是从Redash中我得到了错误：

 Connection Test Failed:
 could not connect to server: Connection refused Is the server running 
 on host "localhost" (::1) and accepting TCP/IP connections on port 
 5432? could not connect to server: Connection refused Is the server 
 running on host "localhost" (127.0.0.1) and accepting TCP/IP 
 connections on port 5432?

任何想法可能是什么问题？我将docker用于我的本地Redash，这可能会导致问题，但是我也从redash.io中得到了相同的错误。

这是我的docker-compose文件：

# This configuration file is for **development** setup. For production, refer to
# docker-compose.production.yml.
