Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

PostgreSQL Is Enough
WalEx instead of pub/sub (listen/subscribe): https://github.com/cpursley/walex
Supavisor connection pooler: https://github.com/supabase/supavisor

Introducing Read Replicas
To make use of your read replicas, copy your connection string for the read replica, update your apps to use the new read replica and you are done! A unique connection pool is also provisioned for each read replica via Supavisor.

Supavisor 1.0: a scalable connection pooler for Postgres
[I'm on the supabase team]
You can find the code/docs here: https://github.com/supabase/supavisor
This release adds support for
- SQL Parsing
- Load balancing
- support for named prepared statement
- query cancellation
It's also now available on all new databases in Supabase. For some more background on scalability, we have some benchmarks available here:

PgBouncer 1.21.0 released with prepared statement support
PgBouncer maintainer here, so obviously biased. But I think currently PgBouncer should still be the default connection pooler that you choose. There's a few newer options: Odyssey, pgcat, and supavisor. But all focus on a solving 1 or 2 specific problems that PgBouncer did not solve well, while not solving many of the other problems that PgBouncer does solve. So if you have the exact same requirements as the authors of those tools, then switching might be good. But otherwise you should probably continue using PgBouncer.
Supavisor specifically is really immature. It's missing some really core functionality like query cancellations: https://github.com/supabase/supavisor/issues/174
I did a talk on this exact topic at PGConf NYC recently. My slides are here: https://github.com/JelteF/slides/raw/main/2023-10-05-future-...

How to Listen to Database Changes Using Postgres Triggers in Elixir
Phoenix.PubSub is basically a noop service. It really just works. You should try it!
If discovering nodes is difficult in your env, try using a listen/notify libcluster strategy:

Building a Managed Postgres Service in Rust
I've been writing Postgres extensions for a few years now (mostly in C and Python), and I have to say that an important contribution from companies like Tembo and Omnigres is in the area of tooling and boilerplate. From workflows to Dockerfiles [0], that's important for the future of Postgres.
This has been discussed in the past [1], but the Postgres tooling ecosystem has been primarily C-Makefile—mailing list driven, and there used to be a lot of Makefile targets copy-pasting. Whenever major Postgres providers wanted to open source some of their extensions / sub-products. I still feel, however, that a lot of Postgres C-know-how is being slowly forgotten / lost, and I think it will be necessary again soon. Internal things as how Postgres handles varlena, StringInfo, JsonbValue, etc. The core abstractions that make Postgres work.

Ask HN: Who is hiring? (December 2023)
At Omnigres, our north star is to enable developers to laser-focus on business needs instead of fighting technological challenges.
We're fighting the complexity and inefficiencies of contemporary stacks by removing them instead of hiding them.
At the core, we are turning Postgres into an Application Runtime. Why? Because we believe that code and data are inseparable in pretty much all of the line-of-business application systems. Turns out, when done this way, applications work a lot faster, require a lot less maintenance and are simply easier to write.
Our foundation is open source and is available at https://github.com/omnigres/omnigres
We're backed by some great early-stage VCs and looking to onboard people who can move quickly, learn on the go and maintain the focus on the goals. Another way to look at it: we want to meet other pragmatic idealists.

Omnigres: Postgres as a Platform
Couple of questions (with notes): Yes, I'd really like to write code next to the db with more suitable (for task) languages like Python. But at the moment SQL alone is supported..? Could one connect with Jupyter notebook somehow and have a REPL like experience with Omnigres instance?
Also, this [1] seems intriguing. How do containers connect to the db? What would the performance differences to the "internal" approach? Is this feature more like Lambda or for long running processes? Or something else? In any case very interesting.
Thank you!
