Some Name's questions

I've got a kubernetes pod myapp-2390458f-kfjgd I can get access to with kubectl and an instance of a PostgreSQL that can be accessed from within the kubernetes cluster by the name mypos.tgres.com, but it cannot be accessed outside of the cluster.

I'm trying to connect to the PostgreSQL from my laptop, but to my knowledge kubectl port-forward would not work in that case since I can only forward my local port to some pod's port. But it would not forward traffic further to mypos.tgres.com.

Is there a way to forward all traffic to the actual db instance mypos.tgres.com from the pod that can be accessed from my laptop?

What would be the possible solution?

The PostgreSQL is not running as a pod, but on an internal network that is only accessible from the Kubernetes cluster's pods. The Kubernetes cluster is hosted in our own infrastracture, not in a cloud.

I'm new to QEMU and playing around with its chardevs. I faced the option called -chardev pty,id=id. So I tried to create a VM with -chardev pty,id=pty0 and got the message.

char device redirected to /dev/pts/9 (label pty0)

So I tried to send some data to it:

root@super-pc:~# cat /dev/pts/9

and didn't see any output.

What is the use case of this chardev?
