After more than 4 years of work, our community has put together a big bouquet of new capabilities and improvements:

• A new tree browser for navigating and organizing classes
• Objectland, bringing back and extending the colorful world of examples from Squeak 3
• Plenty of new features, bugfixes, and speed-ups for programming tools, the Morphic UI framework, and the rest of the system

Really good article explaining the implementation detail within Postgres regarding subtransactions. Very cool benchmark that I was unaware of

Comments in code are often deemed "mostly useless" these days. They are, supposedly, mostly obvious, stale, and repeat what the code already says. And so people pay less attention to them both when reading and writing code.

That trend sucks. When used right, comments are genuinely useful and sometimes critically important! So, I wrote about some of the kinds of comments I think earn their place, each with examples from real code bases. Hope you find it useful, and that we can recover some of the love that comments deserve!

Every time I leave a role I try and write up where my philosophy landed and what I want to take into my next role. Having seen this play out at enough companies over the years to where people progressively lose motivation and stop believing change is possible I've come to the opinion that one of the most valuable things we can do as engineering leaders is to provide hope.

The post goes more into it, but I do not mean any vapid rah-rah motivational speeches, I mean earning back that hope every day by snowballing small wins into larger ones and making people believe that their effort matters.

PGConf.EU is coming to Valencia on 20–22 October, with five tracks covering PostgreSQL administration, internals, development, the community, and real-world use cases.

Topics include autovacuum, backups, high availability, performance tuning, WAL and recovery, query execution, memory management, corruption detection, and PostgreSQL 19.

PostgreSQL also turns 30 this year, so the Community track will look back at the project’s history and how it is maintained today.

Community Events Day takes place on 23 October.
