Greg Sabino Mullane: Examining Postgres Upgrades with pg_upgrade

15. März 2024 - 14:00

Postgres is an amazing database system, but it does come with a five-year life cycle. This means you need to perform a major upgrade of it at least every five years. Luckily, Postgres ships with the pg_upgrade program, which enables a quick and easy migration from one major version of Postgres to another.

Shaun M. Thomas: PG Phriday: Redefining Postgres High Availability

15. März 2024 - 2:27
What is High Availability to Postgres? I’ve staked my career on the answer to that question since I first presented an HA stack to Postgres Open in 2012, and I still don’t feel like there’s an acceptable answer. No matter how the HA techniques have advanced since then, there’s always been a nagging suspicion in my mind that something is missing. But I’m here to say that a bit of research has uncovered an approach that many different Postgres cloud vendors appear to be converging upon.

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!

15. März 2024 - 1:00

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.

Amit Kapila: A day in the life of a PostgreSQL engineer at Fujitsu – Introducing the blog series

14. März 2024 - 1:56

I am constantly impressed by the talent and commitment of the Fujitsu engineers that work hard to make PostgreSQL the best database in the market. So, I thought that more people should know these passionate professionals, and what a day in their life is like.

Elizabeth Garrett Christensen: Postgres Performance Boost: HOT Updates and Fill Factor

13. März 2024 - 14:00

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

13. März 2024 - 11:49
In a previous post, I mentioned that Postgres databases often have text indexes sorted linguistically rather than bytewise, which is why they need to be reindexed on libc or ICU upgrades. In this post, let’s discuss how to use bytewise sorts, and what are the upsides and downsides of doing so.

Hans-Juergen Schoenig: Enforcing join orders in PostgreSQL

12. März 2024 - 16:20

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

12. März 2024 - 16:00

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.

Robert Bernier: Managing Time Series Data Using TimeScaleDB-Powered PostgreSQL

12. März 2024 - 15:05
PostgreSQL extensions are great! Simply by adding an extension, one transforms what is an otherwise vanilla general-purpose database management system into one capable of processing data requirements in a highly optimized fashion. Some extensions, like pg_repack, simplify and enhance existing features already, while other extensions, such as PostGIS and pgvector, add completely new capabilities.I’d like […]

Ryan Booz: Transforming and Analyzing Data in PostgreSQL

12. März 2024 - 11:07

In our data hungry world, knowing how to effectively load and transform data from various sources is a highly valued skill. Over the last couple of years, I’ve learned how useful many of the data manipulation functions in PostgreSQL can supercharge your data transformation and analysis process, using just PostgreSQL and SQL.

Stefan Fercot: The importance of PostgreSQL timelines

11. März 2024 - 16:28

Flashpoint: have you ever watched a Sci-Fi movie where the main character goes back in time, change something there (i.e. save his mother’s life) and then comes back to present days but arrives in an alternate reality? Applied to PostgreSQL backups, the alternate reality called timeline is a key notion for Point-in-Time Recovery.

Andreas 'ads' Scherbaum: Artur Zakirov

11. März 2024 - 15:00
PostgreSQL Person of the Week Interview with Artur Zakirov: I currently reside in Berlin, Germany, and work at Adjust. I grew up in a village in Bashkortostan, Russia. It is located in a green area far from the hustle of big cities. During my early years I didn’t think about living in big cities. Today it’s hard to imagine myself away from a vibrant city. I moved to Berlin around three years ago. And I lived in Tokyo, Japan, around one year before moving to Berlin.
