Hasura with postgres connection

Hello I was trying to connect Hasura to an already existing database of postgres. I tried all three methods as ENV variables, URL, and connection parameters. note that I have docker of both Hasura and postgres in different
docker-compose: Following are specifications [ { "definition": "name", "message": "connection to the server at "localhost" (127.0.0.1), port 5432 failed: Connection refused\n\tIs the server running on that host and accepting TCP/IP connections?\nconnection to server at "localhost" (::1), port 5432 failed: Cannot assign requested address\n\tIs the server running on that host and accepting TCP/IP connections?\n", "name": "source name", "reason": "Inconsistent object: connection error", "type": "source" } ]

Both docker containers are running and even with the same parameters I was able to connect pgadmin 4 Also I tried with different posts such as 172.17.0.4 because I was showing this IP too for IPv4 even tried with localhost.[enter image description here](https://i.stack.imgur.com/LE3lX.png)

I wanted to get connected with Hasura and postgres who both are running as independent containers in docker.

Start with the docker-compose setup and the reported connection-refused error. Check how Hasura resolves the PostgreSQL host when the containers are separate, using the stated ENV, URL, and connection-parameter configurations. Done means Hasura connects successfully to the existing PostgreSQL database.
