A cascading standby reconnect bug that has been sitting in #PostgreSQL's streaming replication code since version 9.3 (2013) has just been fixed upstream last week by Marco Nenciarini, Esteemed Senior Principal Engineer at EDB, Significant PostgreSQL Contributor, and one of the maintainers of #CloudNativePG: https://www.enterprisedb.com/blog/13-year-old-postgresql-bug-found-running-postgres-kubernetes-cloudnativepg
We cut a primary off from its replicas and the control plane, then watched what actually happened instead of what the docs promised: https://coroot.com/blog/reproducing-split-brain-on-cloudnativepg/
Most of it comes down to two default timers that don't agree with each other. This post explains which ones, and the change that shrinks the window.

Sometimes the best way to learn how something works is to break it.
This week, Coroot CEO Nikolay Sivko tried to take down CloudNativePG replication. Turns out, it’s remarkably resilient: https://coroot.com/blog/fencing-a-cnpg-replica/
Even when the network was severed between a #Postgres replica and its primary, the replica continued to pull from a second WAL source: the S3 backup archive.

It has been a while since I wrote a proper long guide about something I actually love doing.
In September 2025 I wrote up how to run Mastodon on Kubernetes. That blog is gone, the guide survives only in the Web Archive. A text about backups that exists as somebody else's copy. At least it stayed on topic.
So I rewrote all of it against Mastodon 4.6.
The part I got wrong the first time was the most important one: Postgres as a Deployment with a PVC next to it.
Kubernetes sends SIGTERM, Postgres reads that as a smart shutdown and waits for every client to disconnect. Sidekiq never does. Thirty seconds later, SIGKILL and a crash recovery.
CloudNativePG and continuous WAL archiving now, RPO down from 24 hours to minutes. Still no Helm, everything by hand, because I want to understand what runs.
My own instance came off Kubernetes in March, purely on cost. This is the config as it last ran.

A database monitoring graph says replication lag is climbing. It doesn't say whether WAL isn't reaching the replica or is sitting there unapplied.
We built something different. Actionable diagnoses, not detective work at 2AM: https://docs.coroot.com/inspections/postgres/

Followup on this: Looking into Garage first. Very simplified access model, which is not necessarily a bad thing. Seems to work fine with #CloudNativePG (#CNPG). Can create buckets and keys through the API.
Considering putting the time to try write an operator for #Kubernetes that can request buckets from various providers, inspired by StorageClasses and PVCs. Throw a bucket claim manifest in your name space, and receive a secret with credentials for it. Apply to CNPG or Mastodon or whatnot, and Bob's your uncle. Easily request from different providers, either local or remote. I'm thinking MinIO, Garage and perhaps RustFS too. Multi tenancy safe too, somehow.
I really wish someone would step up and build a cloudnative-pg -like tooling for mongodb
it's such a pain to work and maintain a self-hosted when you don't want to pay for the hosted version

I have services in my #homelab that need #postgres quite often. In my #k3s cluster I'm using #cloudnativepg to provision single-use databases for services. What should I do for my services running in #docker? Create a single VM that just runs Postgres and connect them all to it? Provision a single Postgres in k3s and expose it so that docker containers externally can use it?
Move anything that needs postgres to #kubernetes?
#selfhosting can get complicated 😔
The Cloud Native Theatre was FULL for the session by #CloudNativePG maintainer Gabriele Bartolini and HSBC's Laurent Parodi: "From VMs to Kubernetes in a Large Global Bank: A DBA's Journey". Recording coming soon! #PostgreSQL #Kubernetes #DoK

PostgreSQL Berlin March 2026 Meetup

Some time this weekend, we'll be upgrading the #Mastodon #PostgreSQL cluster on #MSTDNDK. The cluster is being managed by #CloudNativePG and upgrades have been successfully tested on multiple other clusters - even upgrades directly from version 15 to 18.
While this is an incredibly smooth and easy process, major upgrades requires that #CNPG takes down the whole database cluster, meaning https://mstdn.dk will be unavailable for a period of time. Exactly how long is unknown, since we've never actually done this before with clusters of this size.
I'll keep you posted and give you fair warning 🙂

We've been running #CloudNativePG at Brella for months now. Honestly? Haven't missed Cloud SQL once.
Failover works, backups work, PgBouncer's built in. It's just #Postgres - no black box nonsense.
Get the flexibility of scaling #PostgreSQL from any point - even a single-primary node - up to multiple nodes across multiple regions.
Our #OpenSource components give you write-anywhere, read-anywhere active-active capabilities with pure #Postgres, and our variety of deployment options mean you can leverage containers (including #Docker compose or #Helm charts with #CloudNativePG), virtual machines, & bare metal to do it.
Learn more: https://www.pgedge.com/get-started
Now, you can use open-source pgEdge components designed for high-availability & multi-master replication combined with #CloudNativePG for cloud-native #PostgreSQL orchestration.
Our goal was to make it easy for developers to adopt powerful open-source and vendor lock-in free solutions.

Как и зачем мы написали собственное опенсорс-решение для бэкапов CloudNativePG в Stackland
Всем привет! В этой статье поговорим про бэкапы PostgreSQL в Kubernetes через призму самого популярного опенсорс-оператора для этой СУБД — CloudNativePG. Мы расскажем о том, как внедрение нового решения на основе WAL-G позволило ускорить резервное копирование и восстановление больших баз данных и поделимся своим опытом доработки CloudNativePG. На связи Иван Архипов, ведущий разработчик в команде платформы данных в Yandex Cloud, и я приглашаю под кат всех, кому интересна эксплуатация PostgreSQL в Kubernetes!

Сколько производительности съедает Kubernetes: сравниваю native PostgreSQL и CloudNativePG в Yandex Cloud
В этой статье я руками сравнил производительность PostgreSQL на «голой» VM в Yandex Cloud и в кластере CloudNativePG в Kubernetes. Один и тот же конфиг, одинаковые ресурсы, fio и pgbench, несколько типов хранилищ — и просадка до ~40% при работе через cnpg. Разбираемся, где теряются TPS: на диске, в сети или в оболочке k8s, показываем все цифры в таблицах и схемах прохождения запроса «до VM» и «до Pod’а» — и в конце честно отвечаем, стоит ли игра свеч.
