My thanks to Jonathan Katz for his presentation, “Trusted Language Extensions for PostgreSQL”, at last week’s Postgres Extension Ecosystem Mini-Summit. As usual I’ve collected the transcript here interspersed with comments from the chat window. First, links!

Learn how to ensure PCI DSS compliance in your PostgreSQL database with these 7 crucial considerations.

The post 7 considerations for PCI DSS compliance in PostgreSQL appeared first on Stormatics.

Yesterday I released v1.6.0 of the pgxn/pgxn-tools Docker image with a new command: pgrx-build-test works much like the existing pg-build-test utility for PGXS extensions, but for pgrx extensions.

There's a thread on hackers about recovering memory consumed by paths. A reference count is maintained in each path. Once paths are created for all the upper level relations that a given relation participates in, any unused paths, for which reference count is 0, are freed. This adds extra code and CPU cycles to traverse the paths, maintain reference counts and free the paths. Yet, the patch did not show any performance degradation.

In an era where data breaches are both costly and damaging to reputations, implementing best practices and robust security measures is crucial. PostgreSQL has emerged as one of the most successful and highly adopted open-source databases, competing with the enterprise standards of Oracle and SQL Server. Its increasing popularity is evident from DBEngine rankings, Stackoverflow […]

PGXN Future Architecture

High-level diagram of the six logical services making up the proposed future extension distribution architecture. The Root Registry sits at the center, providing APIs for the other services to consume for their own use cases. Trusted instances of those services submit additional data about extensions via the Interactions service to enhance and enrich the service to better inform and delight users.

Compile & Install pg_tle on PostgresPostgreSQL is a powerful database, but sometimes you want to extend its functionality with custom features, and that's where extensions like pg_tle (Trusted Language Extensions) come into play.If you're new to pg_tle, here's a quick round-up of why it makes sense for you - See Unlock PostgreSQL Superpowers with pg_tle.Given the power of&

For those who have studied ERD-lore, it's not new that a relational database is very much like a graph. But it has taken SQL, more than 30 years since it became a standard and almost half a century since its inception to incorporate construct that will allow a DataBase to be treated as a Graph, DBaaG. This is surprising given that SQL was developed as language for relational databases which are modeled using ER diagrams. Better late than never. SQL/PGQ has arrived as 16th part of SQL:2023.

The material and the videos are now online!

PgTraining Free Online Event: Material Available

The past Friday, on April 19th, we did our fourth edition of the webinar dedicated entirely to PostgreSQL, provided by PgTraining.

As in the previous editions, we had three talks and an open discussion at the end. The talks (all in italian) were:

As promised in the CFP for POSETTE: An Event for Postgres 2024, all of the talk selection decisions were emailed out on April 17th. Our talk selection work has now concluded, with the possible exception of accepting proposals from the Reserve list.

Last week I appeared on s02e03 of the Hacking Postgres podcast.

The experience I had after my independent Consulting gig for 10 years working in companies was, like, bringing up other people and being supportive of other people and hearing from a diversity of voices and perspectives makes everything better.

PGDay UK 2024 will take place in London on September 11th at the Cavendish Conference Centre, London, UK.

Our Call for Papers and Call for Sponsors are now open.

We are accepting proposals for talks in English. Each session will last 50 minutes, and may be on any topic related to PostgreSQL. The submission deadline is 9th June 2024 23:59:59 BST. Selected speakers will be notified on or before July 1st, 2024. Please submit your proposals here:

The first two articles in this series demonstrated how PostgreSQL is a capable tool for ELT – taking raw input and transforming it into usable data for querying and analyzing. We used sample data from the Advent of Code 2023 to demonstrate some of the ELT techniques in PostgreSQL.

Sometimes it happens: I write something in a rush, and present it in a not-optimal way. And then I get advices!

Using PL/Java: need for clarifications

On January, I wrote an article about installing PL/Java on Rocky Linux, and about some of the difficulties I had in achieving a fully operational installation, even if I did not dig enough into the problems that I encountered.

pg_tle - A Must-Know for DevelopersPostgreSQL is a fantastic database, packed with features. But sometimes, you need to add a little something extra – a custom function, a specialized data type, or maybe a procedure written in your favorite programming language. That's traditionally where PostgreSQL extensions come in. But for developers working with managed databases (like Amazon RDS),

What is Visibility?

Simply put, the visibility refers to whether a row of data (Heap Tuple by default) should be displayed to the user in certain states, backend processes, or transactions.

For example,

1. Overview

In my previous blogs, I discussed Setting up a debugging environment in PostgreSQL to better understand OpenSSL APIs, Enhance PostgreSQL TLS Security with OCSP Stapling, and How to setup TLS connection for PostgreSQL.

You could be saving money every month on databases costs with a smarter data retention policy. One of the primary reasons, and a huge benefit of partitioning is using it to automatically archive your data. For example, you might have a huge log table. For business purposes, you need to keep this data for 30 days. This table grows continually over time and keeping all the data makes database maintenance challenging. With time-based partitioning, you can simply archive off data older than 30 days.

We explore PostgreSQL Internals in detail - its processes, architecture, the different types of processes available, and their respective responsibilities.
