What Hacker News says
17 sourcesJust use https://github.com/yandex/odyssey :) It's a scalable PgBouncer.
In We scaled PgBouncer to 4x throughputhttps://github.com/yandex/odyssey - Scalable PostgreSQL connection pooler with prepared statements in transaction pooling mode
In Open sourcing our fork of PgBouncerThis is /extremely/ uncharitable. It depends more on the project.
For example, both Go and .NET are very well written engineering achievements with thorough documentation. Many, many other deeply influential projects have also been absorbed by the Apache Foundation or other FOSS initiatives.
Furthermore, every software megacorp has boat loads of teams working on hundreds even thousands (!) of different open source projects. The quality naturally varies.
Let me pick two more esoteric projects as a point of comparison.
Yandex Odyssey [0] an advanced multi-threaded PostgreSQL connection pooler and request router. Figuring out how exactly and when to use this is not quite clear. There is no "getting started" guide for this package. There is barely any explanation for how it works or what it does.
pg_auto_failover [1] run by Citus (owned by Mi

crosoft) monitors and manages automated failover for a Postgres cluster. This repo even has diagrams explaining the workflow and complete instructions.
Frankly, it's unreal just how much code is open nowadays especially from the giants.
Visual Studio, for example, had been under lockdown for 20 years. Now Visual Studio Code is being developed in the open and has extremely thorough documentation that walks developers through the entire build process in painstaking detail.[2] This is a blazing fast editor written in JavaScript of all things! Or consider TypeScript, an incredible engineering feat. There is an entire repo dedicated to engineering notes on how the compiler works with links to interesting feature contributions and a video! [3]
I'm only picking Microsoft here as the primary example since you dumped on them the hardest.
*No other industry does this. It is absolutely wild how much copyleft influenced software culture.*

In Show HN: PgCat, Postgres pooler with sharding, load balancing and failoverOdyssey could work fine on arm, but we've a small ASM function https://github.com/yandex/odyssey/blob/master/third_party/ma... . We need to reimplement it for ARM64 or at least fallback on some generic context swap.
In Scalable PostgreSQL Connection PoolerThanks for the pointers! I did play around a bit but it seems to segfault and I'm not sure how to proceed.
https://github.com/yandex/odyssey/issues/361
In Scalable PostgreSQL Connection Pooleris the Dockerfile not production ready ? https://github.com/yandex/odyssey/blob/master/docker/Dockerf...
i mean i see valgrind, vim, etc in there. this would be a very fat dockerfile.
It seems that way - https://github.com/yandex/odyssey/issues/29#issuecomment-764...
>But it's hard to "bless" some "official" as image: no one from active contributors uses Odyssey in Docker to maintain it thoroughly.
OTOH pgbouncer docker images are rock-solid in production.
Very quickly updated to track upstream.
e.g. the Bitnami ones - https://hub.docker.com/r/bitnami/pgbouncer/ which also have CVE security scans https://quay.io/repository/bitnami/pgbouncer?tab=tags
Microsoft releases an officially supported k8s sidecar of pgbouncer - https://hub.docker.com/_/microsoft-azure-oss-db-tools-pgboun...
