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.

Introducing Read Replicas
Streaming replication minimizes replication lag, while file-based log shipping provides a fallback. For file-based log shipping, we use our existing Point In Time Recovery (PITR) infrastructure. We regularly archive files from the primary using WAL-G, an open source archival and restoration tool, and ship the WAL files to S3.

Go 1.18 (Go with generics) no blocking issues left
While everyone fears some new spiral of complexity, it's nice

Add a few type constraints, throw out a few type casts along with the error handling

A rough proposal for sum types in Go, from a Rust compiler engineer
When it's occasionally useful return (type, err), but generally the two results are distinct so there's no need to return two results in the general case when one suffices
Indeed, I recently updated some code to return a relevant value in the error case: https://github.com/wal-g/wal-g/pull/1143/files#diff-d896e5d5...

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:
https://supabase.com/blog/supavisor-1-million

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:
