Neues vom PostgreSQL Planet
David Wheeler: Building Trunk
This week, my fellow Tembonaut Ian Stanton will present the extension ecosystem mini-summit talk, “Building Trunk: A Postgres Extension Registry and CLI”.
Pierre Ducroquet: Look ma, I wrote a new JIT compiler for PostgreSQL
Sometimes, I don’t know why I do things. It’s one of these times. A few months ago, Python 3.13 got its JIT engine, built with a new JIT compiler construction methodology (copy-patch, cf. research paper). After reading the paper, I was sold and I just had to try it with PostgreSQL. And what a fun ride it’s been so far. This blog post will not cover everything, and I prefer other communication methods, but I would like to introduce pg-copyjit, the latest and shiniest way to destroy and segfault speed up your PostgreSQL server.
Hubert 'depesz' Lubaczewski: What the hell is transaction wraparound?
Adrien Nayrat: Back from pgDay Paris 2024.
I’m back from pgDay Paris. I really enjoyed this edition. I’d already come to the 2019 one, and I must say I wasn’t deceived. As a reminder, pgDay Paris is an international conference. Presentations are in English, attracting more English speakers and audiences.
Jonathan Katz: Distributed queries for pgvector
The past few releases of pgvector have emphasized features that help to vertically scale, particularly around index build parallelism. Scaling vertically is convenient for many reasons, especially because it’s simpler to continue managing data that’s located within a single instance.
Henrietta Dombrovskaya: The Security Talk Maiden Voyage
First of all here are the presentation slides:
Bertrand Drouvot: Postgres 17 highlight: Logical replication slots synchronization
PostgreSQL 17 will normally (as there is always a risk of seeing something reverted in the beta phase) include this commit: Add a new slot sync worker to synchronize logical slots.
Sai Srirampur: Enterprise-grade Replication from Postgres to Azure Event Hubs
David Wheeler: Mini Summit One
Great turnout and discussion for the first in a series of community talks and discussions on the postgres extension ecosystem leading up to the Extension Ecosystem Summit at pgconf.dev on May 28. Thank you!
The talk, “State of the Extension Ecosystem”, was followed by 15 minutes or so of super interesting discussion. Here are the relevant links:
semab tariq: PostgreSQL Internals Part 1: Understanding Database Cluster, Database and Tables
Learn about database clusters, databases, and tables to optimize performance and unleash the full potential of PostgreSQL for your projects.

Shaun M. Thomas: PG Phriday: Redefining Postgres High Availability
Luca Ferrari: PgTraining Online Event 2024 (italian)
We are back with another event!
PgTraining Online Event 2024 (italian)
PgTraining, the amazing italian professionals that spread the word about PostgreSQL and that I joined in the last years, is organizing another online event (webinar) on next 19th April 2024.
Following the success of the previous edition(s), we decided to provide another afternoon full of PostgreSQL talks, in the hope to improve the adoption of this great database.
Luca Ferrari: pgagroal command refactoring (again!) and a new contributor!
Changes in pgagroal-cli and pgagroal-admin.
pgagroal command refactoring (again!) and a new contributor!Last year I introduced a way in pgagroal-cli and pgagroal-admin to arrange commands in a more consistent and manageable way, deprecating some commands too.
Today, a new contributor to the project, Henrique de Carvalho, committed a patch that greatly improves the way commands are handled internally.
Umair Shahid: Understanding the PostgreSQL Query Planner to Improve Query Performance
Learn how the PostgreSQL query planner estimates costs and leverages configuration parameters for efficient data retrieval and increased database performance.

Elizabeth Garrett Christensen: Postgres Performance Boost: HOT Updates and Fill Factor
There’s a pretty HOT performance trick in Postgres that doesn’t get a ton of attention. There’s a way for Postgres to only update the heap (the table), avoiding having to update all the indexes. That’s called a HOT update, HOT stands for heap only tuple.
Daniel Vérité: Using binary-sorted indexes
Hans-Juergen Schoenig: Enforcing join orders in PostgreSQL
After the pgconfeu23 in Prague – which has been an excellent event – I decided to share some of the things I presented as a blog post to maybe shed some light on some of those topics. One of those ideas presented was the way PostgreSQL handles joins and especially join orders. Internally the PostgreSQL does a good job to optimize queries but how does it really work?
Francesco Tisiot: How to use pgbench to test PostgreSQL® performance
Testing a database performance is a must in every company. Despite everyone's needs beings slightly different, a good starting point for PostgreSQL® database is using pgbench: a tool shipped with the PostgreSQL installation that allows you to stress test a local or remote database.
This blog post showcases how to install (on a Mac) and use pgbench to create load on a remote PostgreSQL database on Aiven.
