What do you think AWS is doing behind the scenes when you run Postgres RDS? It's their own equivalent of a "K8S operator" managing it. They make bold claims about how good/reliable/fault-tolerant it is, but the truth is that you can't actually test or predict its failure modes, and it can fail and fails badly (I've had it get into a weird state where it took 24h to recover, presumably once an AWS guy finally SSH'd in and fixed it manually - I could've done the same but without having to wait 24h).
