semab tariq: Important PostgreSQL Parameters: Understanding Their Importance and Recommended Values
Have you ever experienced your database slowing down as the amount of data increases? If so, one important factor to consider is tuning PostgreSQL parameters to match your specific workload and requirements.
Ants Aasma: End of the road for PostgreSQL streaming replication?
PostgreSQL streaming replication is pretty fast. It is based on transaction log (WAL) and crash recovery mechanism. This work is something the primary must handle anyway for safe operation, so the overhead on the primary side is negligible. The only extra work is pushing WAL out onto the network in addition to disk.
Pavel Luzanov: PostgreSQL 18: part 2 or CommitFest 2024-09
Statistically, September CommitFests feature the fewest commits. Apparently, the version 18 CommitFest is an outlier. There are many accepted patches and many interesting new features to talk about.
If you missed the July CommitFest, get up to speed here: 2024-07.
Andreas 'ads' Scherbaum: Social Media Channels
PostgreSQL Europe will stop posting on Twitter/X. This includes our main accounts, and all conference accounts we operate or help to organize. . Recent changes to the platform's policies steadily transform Twitter/X into a space which we believe spreads a lot of hate and is no longer aligned with our community spirit and values.

Grant Fritchey: Free PostgreSQL Performance Monitoring with pgNow
I’ve been putting together a new PostgreSQL session called “Performance Monitoring for the Absolute Beginner.” There are several ways to get an understanding of how well your queries are running in PostgreSQL, but, frankly, all of them are a bit of a pain to someone coming from the land of Extended Events (ah, my one […]
The post Free PostgreSQL Performance Monitoring with pgNow appeared first on Grant Fritchey.
Stefan Fercot: pgBackRest preview: verify recovery target timeline on restore
Have you ever faced timeline issues during PostgreSQL recovery? It can be frustrating to complete a restore only to discover during recovery that the timeline is invalid, which often results in an error message like this:
Federico Campoli: PGDay Napoli 2025
Finally I found time to get a grip on the issues I had with gohugo and get my blog operational again.
I’m taking the occasion to write about a project I care a lot as it’s strictly related with my hometown, the upcoming PGDay Napoli.
Henrietta Dombrovskaya: February Meetup: Postgres Full Text Search
Every time I host a Postgres Meetup, I am thankful to everyone who comes. But today, I am especially thankful because so many people showed up despite the snowstorm! Staying after work to attend a meetup in these weather conditions demonstrates true dedication!
Many thanks to Steve Zelaznik for his wonderful presentations (recording will be available!), and thanks to all participants for listening, asking insightful questions, and a lively discussion afterward!
Peter Eisentraut: How about trailing commas in SQL?
Anecdotally, this might be the most requested feature in SQL: Allow some trailing commas.
The classic example is
SELECT a, b, c, -- here FROM ...Another one is
CREATE TABLE tab1 ( a int, b int, c int, -- here )There might be a few other popular ones. (Please send feedback.)
Laurenz Albe: Dealing with the PostgreSQL error "found xmin ... from before relfrozenxid ..."
I have seen the error from the title reported often enough. If you are not familiar with the internals of PostgreSQL, the message will confuse you: what are xmin and relfrozenxid? Why is it a problem if one is before the other? So I think that it is worth the effort to write an article about the problem and what the error means. I'll also show you how to cope with the situation and fix the error.
Regina Obe: Learning PostgreSQL from AI and JSON exploration
After reading Paul's teasing article on Accessing Large Language Models with AI and testing out his code, I decided I should probably stop fighting this AI smothering. I still have a distrust of AI services but downloading an AI model and using on my own local desktop or server is nice and I can break bread with that. One use I tried is using AI to generate fake data and it did a pretty decent job.
Paul Ramsey: The Early History of Spatial Databases and PostGIS
For PostGIS Day this year I researched a little into one of my favourite topics, the history of relational databases. I feel like in general we do not pay a lot of attention to history in software development. To quote Yoda, “All his life has he looked away… to the future, to the horizon. Never his mind on where he was. Hmm? What he was doing.”
Brian Pace: Postgres Parallel Query Troubleshooting
Postgres' ability to execute queries in parallel is a powerful feature that can significantly improve query performance, especially on large datasets. However, like all resources, parallel workers are finite. When there aren't enough available workers, Postgres may downgrade a parallel query to a serial (non-parallel) execution. This sounds reasonable unless the performance of the downgraded query is well beyond the required response times needed by the application.
