TimescaleDB is an open-source time-series database extension for PostgreSQL. It is designed to efficiently manage and query time-series data, offering features such as automatic data partitioning, data retention policies, and specialized time-series functions. This extension provides scalability, improved performance, and seamless integration with PostgreSQL, making it a powerful choice for applications dealing with large volumes […]

Adam Johnson: Django: Maybe disable PostgreSQL’s JIT to speed up many-joined queries

9. November 2023 - 1:00

Here’s a write-up of an optimization I made in my client Silvr’s project. I ended up disabling a PostgreSQL feature called the JIT (Just-In-Time) compiler which was taking a long time for little benefit.

8. November 2023 - 16:45

SCRAM was first introduced in Postgres 10 and has been enhanced in most major release since. In summary:

Postgres 10 Added SCRAM-SHA-256 password encryption support for client/server communication and password storage

Postgres 11 Added SCRAM channel binding support

Hans-Juergen Schoenig: Using multiple triggers on the same table in PostgreSQL

7. November 2023 - 10:00

“Developers, developers, developers, …” – let us not remind ourselves of this painful Microsoft presentation which was given by Mr Ballmer some time ago. But what happens if we deploy triggers, triggers, triggers in PostgreSQL? And what happens if we deploy them all on the very same table? That’s an interesting question, and important to consider when writing triggers. What order do the multiple triggers fire in? Let’s understand trigger execution order, but first, the syntax.

Tristen Raab: Managing PostgreSQL Like a Pro: A Kubernetes-based pgAdmin Tutorial

6. November 2023 - 21:04

This blog is aimed at beginners trying to learn the basics of PostgreSQL, pgAdmin and Kubernetes but already have some experience under their belt. For this tutorial, we will assume you have PostgreSQL correctly installed on Ubuntu. All of these steps were done using PostgreSQL 16 (development version), minikube v1.26.3 as the Kubernetes implementation, and pgAdmin 7.8 on Ubuntu 23.04. We’ll go over an example of deploying both a PostgreSQL database and pgAdmin in a Kubernetes cluster to see how we can manage the database.

Bruce Momjian: Explaining the Postgres Query Optimizer Improvements

6. November 2023 - 15:45

I wrote Explaining the Postgres Query Optimizer in 2011, and though I have presented it 22 times, it has changed little over the years. (I created a followup presentation this year.) Periodically, I check my slides to make sure they match the output of the current Postgres version.

Ryan Booz: Getting connected to PostgreSQL for the first time

3. November 2023 - 16:10

PostgreSQL continues to be all the rage in 2023, whether in “vanilla” form of the fully open-source distribution or a variant like Amazon RDS, Neon, Yugabyte, and others. If you’re interested in trying PostgreSQL but only have experience with another database like SQL Server, it can feel a bit daunting to get started.

Robert Bernier: How To Scale a Single-Host PostgreSQL Database With Citus

3. November 2023 - 14:26

When it comes to Citus, successfully building out and scaling a PostgreSQL cluster across multiple nodes and even across data centers can feel, at times, to be an art form because there are so many ways of building it out.

There’s an axiom that I think aptly applies to this situation describing the differences between science and art:

– Science: 1 problem -> 1 solution
– Art: 1 problem -> 1,000 solutions

Bruce Momjian: Presentations from SQL Queries

3. November 2023 - 14:15

Having 61 presentations on my website, I am always looking for efficient ways to create them. For presentations that focus on SQL features, I have found the most efficient method is to first write the SQL queries in the order I want them to appear in my presentation. I then run the queries through psql, and write its output to a text file.

Christopher Winslett: Ruby on Rails Neighbor Gem for AI Embeddings

3. November 2023 - 14:00

Over the past 12 months, AI has taken over budgets and initiatives. Postgres is a popular store for AI embedding data because it can store, calculate, optimize, and scale using the pgvector extension. A recently introduced gem to the Ruby on Rails ecosystem, the neighbor gem, makes working with pgvector and Rails even better.
