Robert Haas: Mentoring Program Updates

9. Juli 2024 - 16:04

Here are a few updates on the mentoring program that I announced in a previous blog post.

Gabriele Bartolini: CloudNativePG Recipe 9 - Inspecting the network and the storage in a CloudNativePG cluster

9. Juli 2024 - 13:20

In this blog post, I delve into the crucial aspects of networking and storage within a CloudNativePG cluster deployed on Kubernetes. I explore how Kubernetes services manage external and internal communications for PostgreSQL clusters, ensuring high availability and seamless failover. Additionally, I examine the role of PersistentVolumeClaims in handling PostgreSQL data storage, offering insights into effective resource management.

Hans-Juergen Schoenig: Using AI to generate data structures for PostgreSQL

9. Juli 2024 - 7:26

Artificial Intelligence is the motto of the day. Everybody is talking about it, everybody seems to know what it means and the insane number of buzzwords floating around on the internet is just mind-boggling. It seems that in some areas of the industry, the number of slides and marketing videos exceeds the number of real-world use cases and sometimes even the amount of code that actually exists.

Claire Giordano: Say hello to the Talking Postgres podcast

9. Juli 2024 - 2:03

The TL;DR of this blog post is simple: the “Path To Citus Con” podcast for developers who love Postgres has been renamed—and the new name is Talking Postgres.

And if you’re just hearing about the Talking Postgres podcast for the first time, it is a monthly podcast for developers who love Postgres, with amazing guests from the Postgres world who talk about the human side of Postgres, databases, and open source.

Sergey Pronin: Automated Major Version Upgrades in Percona Operator for PostgreSQL

8. Juli 2024 - 17:41
PostgreSQL major versions are released every year, with each release delivering better performance and new features. With such rapid innovation, it is inevitable that there will be a need to upgrade from one version to another. Upgrade procedures are usually very complex and require thorough planning. With the 2.4.0 release of Percona Operator for PostgreSQL, […]

Andreas 'ads' Scherbaum: Grant Zhou

8. Juli 2024 - 16:00
PostgreSQL Person of the Week Interview with Grant Zhou: I was born in Qingdao, China, and have been living in Vancouver, Canada since 2013. I am the founder of Highgo Software North America and lead the company’s PostgreSQL open source development team, focusing on PostgreSQL contributions and the IvorySQL project.

David Wheeler: Introducing Go SQL/JSON Path and Playground

8. Juli 2024 - 15:59

For a personal project, I needed to parse and execute PostgreSQL-compatible jsonpath expressions.1 So I’ve spent just about every spare evening and weekend the last several months porting Postgres jsonpath to Go, and it’s finally ready to ship.

Tomas Vondra: Basics of Tuning Checkpoints

8. Juli 2024 - 14:00
On systems doing non-trivial number of writes, tuning checkpoints is crucial for getting good performance. Yet checkpoints are one of the areas where we often identify confusion and configuration issues, both on the community mailing lists and during support and consulting for our customers. This post is meant to explain what checkpoints are - the purpose and how the database implements that - and then also how to tune them.

Elizabeth Garrett Christensen: Parallel Queries in Postgres

8. Juli 2024 - 12:00

Many folks are surprised to hear that Postgres has parallel queries out of the box. This was released in small batches across a half dozen versions of Postgres, so the major fanfare for having parallelism got a little bit lost.

Andrei Lepikhov: Why PostgreSQL prefers MergeJoin to HashJoin?

8. Juli 2024 - 2:01

Today's post is sparked by a puzzling observation: users, especially those who use an abstraction layer like REST or ORM library to interact with databases, frequently disable the MergeJoin option across the entire database instance. They justify this action by citing numerous instances of performance degradation.

Radim Marek: Gentle Introduction to Window Functions in PostgreSQL

7. Juli 2024 - 2:00

Understanding the relationship between data points is crucial. For instance, you might need to identify the most recent orders for each customer or track changes in sensor readings over time. Unlike aggregate functions, which summarise data into a single row, it is window functions that allow you to analyse data while preserving each row’s details. This is the core of the logic, but don’t worry if you struggle to imagine the difference, as we will cover all of it in this article.
