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.

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
