Or CDN, queues, log service, observability, distributed storage. I am not even sure what the people in the on-prem vs cloud argument think. If you need a highly specialised infra with one or two core services and a lower tier network is ok then on-prem is ok. Otherwise if is a never ending quest to re-discover the millions of engineering hours went into building something like AWS.
Is it though? This is a genuine question. My intuition is that the investment of time / stress / risk to become good at this is unlikely to have high ROI to either the person putting in that time or to the business paying them to do so. But maybe that's not right.
Managing the PostgreSQL databases is a medium to low complexity task as I see it.
Take two equivalent machines, set up with streaming replication exactly as described in the documentation, add Bacula for backups to an off-site location for point-in-time recovery.
We haven't felt the need to set up auto fail-over to the hot spare; that would take some extra effort (and is included with AWS equivalents?) but nothing I'd be scared of.
Add monitoring that the DB servers are working, replication is up-to-date and the backups are working.

Same here. But, I assume you have managed PostgreSQL in the past. I have. There are a large number of people software devs who have not. For them, it is not a low complexity task. And I can understand that.
I am a software dev for our small org and I run the servers and services we need. I use ansible and terraform to automate as much as I can. And recently I have added LLMs to the mix. If something goes wrong, I ask Claude to use the ansible and terraform skills that I created for it, to find out what is going on. It is surprisingly good at this. Similarly I use LLMs to create new services or change configuration on existing ones. I review the changes before they are applied, but this process greatly simplifies service management.

I'd say needing to read the documentation for the first time is what bumps it up from low complexity to medium. And then at medium you should still do it if there's a significant cost difference.
For what it's worth, I have also managed my own databases, but that's exactly why I don't think it's a good use of my time. Because it does take time! And managed database options are abundant, inexpensive, and perform well. So I just don't really see the appeal of putting time into this.
This sounds medium to high complexity to me. You need to do all those things, and also have multiple people who know how to do them, and also make sure that you don't lose all the people who know how to do them, and have one of those people on call to be able to troubleshoot and fix things if they go wrong, and have processes around all that. (At least if you are running in production with real customers depending on you, you should have all those things.)
With a managed solution, all of that is amortized into your monthly payment, and you're sharing the cost of it across all the customers of the provider of the managed offering.
Personally, I would rather focus on things that are in or at least closer to the core competency of our business, and hire out this kind of thing.
You are right. Are you actually seriously considering whether to go fully managed or self managed at this point? Pls go AWS route and thank me later :)

this part is actually scariest, since there are like 10 different 3rd party solutions of unknown stability and maintanability.
I really do not think so. Most startups should rather focus on their core competency and direct engineering resources to their edge. When you are $100 mln ARR then feel free to mess around with whatever db setup you want.
