How to Setup OpenShift Route/Direct URL to Connect to PostgreSQL Databases

I am working on a project right now for GE Aerospace where I need to setup a Route in OpenShift and create a Direct URL to connect to Postgres databases externally and use that to connect to the databases instead of using an IP address. OpenShift Routes are designed for HTTP/S-based traffic, not raw TCP protocols such as PostgreSQL. I tried using a passthrough route, but it is still failing. Can someone help me configure this properly, or tell me if this is even possible?

Thank you!
