All that emotionality adds is that you get the illusion of a friend - a friend that can't help you in any way in the real world and who's confidentiality is as strong as the privacy policies & data security of the company running it - which often ultimately trends towards 0.
Smart Neutral Voice Assistants could be a great help, but none of it requires "emotionality" and trying to build a "human connection" with the user. Quite the contrary: the more emotional a voice, the easier it is to misuse it for scams, faking rapport and in general make you "addicted" to loop you in babble with it.
The truth is that people who care about port forwarding are such a small minority -- especially now that P2P file sharing has lost its hype -- that they don't make a visible dent in the rate of IPv4 exhaustion.
I'll be honest it's not documented as well as it could, some concepts like the archive process and the replication setup took me a while to understand. I also had trouble understanding what roles the various tools played. Initially I thought I could roll my own backup but then later deployed pgBackrest. I deployed and destroyed VMs countless times (my ansible playbook does everything from VM creation on proxmox / hetzner API to installing postgres, setting up replication).
What is critical is testing your backup and recovery. Start writing some data. Blow up your database infra. See if you can recover. You need a high degree of automation in your deployment in order to gain confidence that you won't lose data.
My deployment looks like this: * two Postgres 16 instances, one primary, one replica (realtime replication) * both on Debian 12 (most stable platform for Postgres according to my research) * ansible playbooks for initial deployment as well as failover * archive file backups to rsync.net storage space (with zfs snapshots) every minute * full backups using pgBackrest every 24hrs, stored to rsync.net, wasabi, and hetzner storage box.
As you can guess, it was kind of a massive investment and forced me to become a sysadmin / DBA for a while (though I went the devops route with full ansible automation and automated testing). I gained quite a bit of knowledge which is great. But I'll probably have to re-design and seriously test at the next postgres major release. Sometimes I wonder whether I should have just accepted the cost of cloud postgres deployments.
