Manually Installing PostgreSQL from Packages

I'm in the process of bringing my server to life. I have already installed Proxmox onto it and now I'm in the bootstrapping stage whereby I'm planning to manually install a minimum number of VMs to get a minimal amount of services going to be able to access the internet and start using IaC. Problem is, one of the services is a PostgreSQL database. I ran: apt-cache rdepends postgresql This resulted in dozens of dependencies. Not something I want to do manually. Or should I bite the bullet and have at it? Is installing a bunch of packages frowned upon? Just to elaborate, my server at the moment, doesn't have internet access. So I was planning on doing offline installs of the minimum set of VMs with PostgreSQL being on one of these VMs.
