Connecting do default autodevops postgess


I have just started new project with autodevops with GKE, but being new to kubernetes/helm/ingress stack i have some troubles with it.

What is the best way to externally manage stagging/production postgres database preconfigured by gitlab ?

I think ingress should be able to proxy database connection, but for now all my attempts to do it failed. Does anyone managed to configure proxy connection or any other way to reach database from outside kubernetes cluster ?
