Citus is not ACID but Eventually Consistent
Citus doesn't provide fault tolerance. Each shard is a monolithic PostgreSQL. To reduce downtime on failures, you can protect each shard with a standby database. As this is a complex configuration, Patroni can help. For this lab I'll use the Citus+Patroni docker-compose-citus.yml from https://github.com/zalando/patroni.git:

How to create postgres cluster in docker swarm?
We have been using stolon + consul for years without issue in our swarm environments. It may also be possible with patroni.

Why PostgreSQL High Availability Matters and How to Achieve It
one of the solutions which made it pretty simple for us to run postgresql in a ha environment (mostly in k8s, but works standalone as well) is zalandos patroni: https://github.com/zalando/patroni it's really solid and worked for us for a few years already.
or for k8s their operator: https://github.com/zalando/postgres-operator (docker image: https://github.com/zalando/spilo) we've also tried other operators which were easier to get started, but they failed miserably (crunchyrolls operator is basically based on the zalando one)

Docker: Patroni + HAProxy + Etcd + PgBouncer
Hello. I am currently using this docker-compose model from Zalando repository. It does not include PgBouncer in its architecture by default. I've been trying to find a containerized implementation involving Patroni, HAProxy, Etcd and PgBouncer. I didn't find anything solid so far.

Can someone share experience configuring Highly Available PgSQL?
General purpose: Patroni - Set up your own etcd + HAProxy + Patroni + Postgres components and it'll generally manage itself after that.
- Patroni Version 3.0.0 Released
- Any self hostable postgres clustering, replication and fail over system?

Postgresql HA using repmgr and Keepalived
I don't have a great answer for you except that it sounds like you are trying to create your own version of patroni. Is there a good reason to not just use patroni?

Testing Patroni strict synchronous mode 👉🏻 you must handle invisible commit and read split brain
git clone https://github.com/zalando/patroni.git cd patroni docker build -t patroni . docker-compose up -d

Any recommandation Postgres Operator ?
I actually used Patroni on Openshift in my company. To be update with the latest version we created our helm chart.

UUIDv7 is coming in PostgreSQL 17
> Integers don't scale because you need a central server to keep track of the next integer in the sequence.
They most assuredly do scale. [0]
Also, Slack is built on MySQL + Vitess [1], the same system behind PlanetScale, which internally uses integer IDs [2].
