Hubert 'depesz' Lubaczewski: Waiting for PostgreSQL 19 – Sequence synchronization in logical replication.
Hans-Juergen Schoenig: PostgreSQL 18: More performance with index skip scans
PostgreSQL 18 brings a couple of performance related features to the table which will help applications to run more efficiently, providing a better and more enjoyable user experience. One of those performance features is called “skip scans”. Most of you might ask yourself at this point: Wow, sounds cool, but what is a skip scan? The purpose of this post is to shed some light and explain how this works, what it does and most importantly: How one can benefit from this feature in real life.
Peter Eisentraut: Waiting for SQL:202y: GROUP BY ALL
Making GROUP BY a bit easier to use is in my experience among the top three requested features in SQL.
Like, if you do
CREATE TABLE t1 (a int, b int, ...); SELECT a, avg(b) FROM t1 GROUP BY a;the column list in the GROUP BY clause doesn’t convey much information. Of course you wanted to group by a, there is no other reasonable alternative. You can’t not group by a because that would be an error, and you can’t group by things besides a, because there is nothing else in the select list other than the aggregate.
Nikolay Samokhvalov: #PostgresMarathon 2-013: Why keep your index set lean
Your API is slowing down. You check your database and find 42 indexes on your users table. Which ones can you safely drop? How much performance are they costing you? Let's look at what actually happens in Postgres when you have too many indexes.
If you're a backend or full-stack engineer, you probably don't want to become an indexing expert — you just want your API fast and stable, without babysitting pg_stat_user_indexes.
Ian Barwick: PgPedia Week, 2025-11-09
This quarter's round of minor releases are expected later this week. Note this will be the last minor release for PostgreSQL 13 .

Elizabeth Garrett Christensen: Postgres Internals Hiding in Plain Sight
Postgres has an awesome amount of data collected in its own internal tables. Postgres hackers know all about this - but software developers and folks working with day to day Postgres tasks often miss out the good stuff.
The Postgres catalog is how Postgres keeps track of itself. Of course, Postgres would do this in a relational database with its own schema. Throughout the years several nice features have been added to the internal tables like psql tools and views that make navigating Postgres’ internal tables even easier.
Jimmy Angelakos: pg_statviz 0.8 released with PostgreSQL 18 support
I'm happy to announce release 0.8 of pg_statviz, the minimalist extension and utility pair for time series analysis and visualization of PostgreSQL internal statistics.
This release adds support for PostgreSQL 18, adapting to significant catalog view changes introduced in this release:
Jobin Augustine: PostgreSQL 13 Is Reaching End of Life. The Time to Upgrade is Now!
Paul Ramsey: PostGIS Performance: Improve Bounding Boxes with Decompose and Subdivide
In the third installment of the PostGIS Performance series, I wanted to talk about performance around bounding boxes.
Geometry data is different from most column types you find in a relational database. The objects in a geometry column can be wildly different in the amount of the data domain they cover, and the amount of physical size they take up on disk.

Daniel Vérité: Producing UUIDs Version 7 disguised as Version 4 (or 8)
Ian Barwick: PgPedia Week, 2025-10-19
Due to an unfortunate recent visitation by the Virus of the Decade (so far), I have a backlog of these which I'm trying to work through, so in the remote chance anyone is waiting with bated breath for the newest editions, my apologies. Normal service will be resumed as soon as humanly possible.
Henrietta Dombrovskaya: October PUG Recording
Almost a month late, but I hope you enjoy it!
Chris Travers: NUMA, Linux, and PostgreSQL before libnuma Support
This series covers the specifics of running PostgreSQL on large systems with many processors. My experience is that people often spend months learning the basics when confronted with the problem. This series tries to dispel these difficulties by providing a clear background into the topics in question. The hope is that future generations of database engineers and administrators don’t have to spend months figuring things out through trial and error.
Deepak Mahto: PostgreSQL Partition Pruning: The Role of Function Volatility
In one of our earlier blogs, we explored how improper volatility settings in PL/pgSQL functions — namely using IMMUTABLE, STABLE, or VOLATILE — can lead to unexpected behavior and performance issues during migrations.
Hans-Juergen Schoenig: Counting Customers in PostgreSQL
As a database consulting company, we are often faced with analytics and reporting related tasks which seem to be easy on the surface but are in reality not that trivial. The number of those seemingly simple things is longer than one might think, especially in the area of reporting
Mayur B.: ALTER Egos: Me, Myself, and Cursor
I pushed the most boring change imaginable, add an index. Our CI/CD pipeline is textbook ==> spin up a fresh DB, run every migration file in one single transaction, in sequential manner. If anything hiccups, the whole thing rolls back and the change never hits main. Foolproof autotests.
