Ever since CockroachDB changed their license, I'm searching for alternatives. PostgreSQL is an obvious choice but is there a good HA solution? What people usually do for HA with PostgreSQL or do they just not care about it? I tested Patroni, which is the most popular one in my knowledge, but found some HA issues that makes me hesitate to use: https://www.binwang.me/2024-12-02-PostgreSQL-High-Availabili...

Patroni for most cases. At Heroku we have our own control plane to manage HA and fencing which works very reliably. I also like the approach the Cloud Native PG folks have taken with implementing it in the k8s API via the instance manager[1].
Other options like Stolon or repmgr are popular too. Patroni is, despite the Jepsen testing, used well without issues in the majority of circumstances. I wouldn't over think it.
