Shaun M. Thomas: PG Phriday: Kubernetes Killed the High Availability Star
Postgres Conference Seattle 2024 partnered up with PASS this year to present a united database front. They accepted my “Kubernetes Killed the High Availability Star” talk, which I graciously gave on the last day of the conference.
Robert Haas: 2025.pgconf.dev needs your submissions!
The call for proposals for 2025.pgconf.dev has been extended to January 6, 2025, otherwise known as "very soon". I'm writing this post to encourage you to submit, if you haven't done so yet, regardless of whether you have submitted to 2024.pgconf.dev or its predecessor, PGCon, in the past.
Abhishek Chanda: pg_power: initialization and basic setup
I have been playing around with the powercap framework. I wrote a postgres extension that shows the energy usage of a query. Postgres has a hook mechanism that allows an extension to override the default executor. This implementation is very simple: the extension records the current energy reading when a query starts and then calls the actual executor that runs the query. When the query finishes, a second hook records the current energy reading.
Shane Borden: Why Isn’t My Query Benefiting from Partition Pruning?
Recently I had a customer come to me with a poorly performing query that had a perfectly fine execution time on Oracle, but once migrated to Postgres the query was slow. Upon investigation, it was found that even though the “WHERE” and “JOIN” clauses had explicitly specified partition keys and were joined on the partition key, “pruning” was only happening on one part of the query.
The setup for the test is at the bottom of the blog post: Jump to Test Case Setup

Shane Borden: Some of My Favorite Things – Postgres Queries
In the spirit of the holiday season, I thought I would write a quick post regarding some of my favorite queries that I use on a day to day basis working on Postgres. Some of these queries I have developed and others were found on the internet (hat tip to those who have previously posted) and further refined.
Many more are found on my github site:

Marco Slot: pg_incremental: Incremental Data Processing in Postgres
Today I’m excited to introduce pg_incremental, a new open source PostgreSQL extension for automated, incremental, reliable batch processing. This extension helps you create processing pipelines for append-only streams of data, such as IoT / time series / event data workloads.
Notable pg_incremental use cases include:
Florent Jardin: Window functions to the rescue
PostgreSQL comes with a variety of functions that allow you to group rows into a “window” and perform calculations on that window. By using these functions, you can create more advanced and efficient queries for analyzing your database.
Michael Banck: Quick Benchmark: Improvements to Large Object Dumping in Postgres 17
Version 17 of PostgreSQL has been released for a while. One of the many features is a change by Tom Lane called “Rearrange pg_dump’s handling of large objects for better efficiency”. In the past, we have seen our customers have several problems with a large number of large objects being a performance issue for dump/restore.
Pavlo Golub: PGDay/MED 2024 Napoli Edition
The first-ever official PostgreSQL conference was held in Italy. Years later, PGDay/MED 2024 brought us back to this inspiring country. I was excited to visit Naples, often called the cradle of pizza and home to some of the finest cuisines in the world. As a self-proclaimed gastronomic geek, this was a bucket-list experience both professionally and personally!

Andrei Lepikhov: Fractional Path Issue in Partitioned Postgres databases
While the user notices the positive aspects of technology, a developer, usually encountering limitations, shortcomings or bugs, watches the product from a completely different perspective.
REGINA OBE: The bus factor problem
One of the biggest problems open source projects face today is the bus factor problem.
I've been thinking a lot about this lately as how it applies to my PostGIS, pgRouting, and OSGeo System Administration (SAC) teams.

Recently, I attended a conference talk about the vibrant ecosystem of PostgreSQL. It was a fascinating presentation, showcasing the incredible breadth of innovation in the PostgreSQL community. Extensions that push the boundaries of functionality, AI integrations within PostgreSQL, advanced connection pools, and robust cluster management tools were all highlighted.
But something vital was conspicuously absent. Can you guess? That’s right—not a single mention of client connectors.

Umair Shahid: VACUUM FULL in PostgreSQL – What you need to be mindful of
If you have worked with PostgreSQL for a while, you have probably come across the command VACUUM FULL. At first glance, it might seem like a silver bullet for reclaiming disk space and optimizing tables. After all, who would not want to tidy things up and make their database more efficient, right?
But here is the thing: while VACUUM FULL can be useful in some situations, it is not the hero it might seem. In fact, it can cause more problems than it solves if you are not careful.
