David Wheeler: Postgres Extensions: Use PG_MODULE_MAGIC_EXT
A quick note for PostgreSQL extension maintainers: PostgreSQL 18 introduces a new macro: PG_MODULE_MAGIC_EXT. Use it to name and version your modules. Where your module .c file likely has:
PG_MODULE_MAGIC;Or:
#ifdef PG_MODULE_MAGIC PG_MODULE_MAGIC; #endifChange it to something like:
Andrew Atkinson: Tip: Put your Rails app on a SQL Query diet
Much of the time taken processing HTTP requests in web apps is processing SQL queries. To minimize that, we want to avoid unnecessary or duplicate queries, and generally perform as few queries as possible.
Think of the work that needs to happen for every query. The database engine parses it, creates a query execution plan, executes it, and then sends the response to the client.
When the response reaches the client, there’s even more work to do. The response is transformed into application objects in memory.
Brandur Leach: Don't mock the database: Data fixtures are parallel safe, and plenty fast
The API powering our Crunchy Bridge product is written in Go, a language that provides a good compromise between productivity and speed. We're able to keep good forward momentum on getting new features out the door, while maintaining an expected latency of low double digits of milliseconds for most API endpoints.

Tomas Vondra: Advanced Patch Feedback Session (APFS) at pgconf.dev 2025
The pgconf.dev conference, a revamp of the original PGCon, happened about two weeks ago. It’s the main event for Postgres developers, and one of the things we’re trying is an Advanced Patch Feedback Session (APFS).
We first tried that last year in Vancouver, and then again in Montreal. But I realized many people attending the conference either are not aware of the event at all, or are not sure what it’s about. So let me explain, and share some reflections from this year.
Karen Jex: PostgreSQL Europe Diversity Task Force (Deep Dive and Updates)
I'm sharing the slides and transcript from my talk about the PostgreSQL Europe Diversity Task Force at PostgreSQL Development Conference 2025.
It's an extended version of the 5 minute lightning talk that I gave at FOSDEM PGDay earlier this year, with some updates on what we've achieved.
If you want a shorter read, feel free to check out the annotated slides from the lightning talk instead!

warda bibi: How to Upgrade Major PostgreSQL Versions: A Practical Production Guide
PostgreSQL versions follow a well-defined five-year support lifecycle. Each major release receives bug fixes, security patches, and minor updates for five years from its initial release date. After that point, the version reaches end-of-life (EOL) and no longer receives official updates.
Henrietta Dombrovskaya: Prairie Postgres Developers Summit
Even before the Community Summit in Montreal, I wanted to organize a Developers Summit at one of our meetups. My inspiration came from the Open spaces at DevOps Day Chicago. I saw how productive the smaller group discussions could be, and wanted to try to discuss different aspects of interactions.
We finally made it happen on May 22! In the meetup announcement, I asked those signing up to vote for topics we wanted to suggest and name additional topics. Then, when a meetup started, we re-voted the topics, and same as in Montreal, the outcome was different :).

Ian Barwick: PgPedia Week, 2025-05-25
Sadly two features were reverted this week:
planner optimization "Partitions pruned by initial pruning are no longer locked" (commit 525392d5 , reverted in commit 1722d5eb ) function pg_get_process_memory_contexts() (commit 042a6629 , reverted in commit fb844b9f ) PostgreSQL 18 articles UUIDv7 Comes to PostgreSQL 18 (2025-05-09) - Gwen ShapiraJan Wieremjewicz: PostgreSQL 18 - Top Enterprise Features (fast read)
So the Beta1 is available for PostgreSQL 18 and while not all the features have to make it to GA, we can surely hope they do!
Taking a close look at what’s coming, here below is the selection of what excites me in particular:
