What needs to be configured for self-hosting multi-instances of temporal server?

Hi, I am studying how to self-host a temporal cluster with a postgres DB.
I managed to get a temporal server running and working, now I want to have multiple server instances.
Are there any configurations I need or will it work just by connecting the multiple instances to the same DB?
A bit of extra context, I cannot use docker and k8s and I am going to self-host it with binary.

Thank you
