Neues vom PostgreSQL Planet

Data privacy regulations such as GDPR, CCPA, and HIPAA have made it increasingly important for organisations to protect personally identifiable information (PII) in their databases. Whether you're creating a development environment from production data, sharing datasets with third parties, or simply trying to minimise risk, you'll often need to anonymise sensitive data whilst maintaining the structure and relationships within your database.I've been working on a tool to address this need: .

On December 11, the PGDay CERN 2026 CfP committee met to finalize the talk selection. The committee members are listed here:

From time to time I see questions from otherwise well informed people about how the PostgreSQL Build farm checks how pg_upgrade checking is done across versions, e.g. how does it check upgrading from release 9.5 to release 18. I realize that this isn't well documented anywhere, so here is a description of the process.

All of the code referenced here can be found at https://github.com/PGBuildFarm/client-code.

PostgreSQL maintenance doesn't have to mean downtime anymore. With pgEdge's zero-downtime node addition, you can perform critical maintenance tasks like version upgrades, hardware replacements, and cluster expansions without interrupting production workloads. Your applications stay online. Your users stay connected.

There is common misconception that troubles most developers using PostgreSQL: tune VACUUM or run VACUUM, and your database will stay healthy. Dead tuples will get cleaned up. Transaction IDs recycled. Space reclaimed. Your database will live happily ever after.

But there are couple of dirty "secrets" people are not aware of. First of them being VACUUM is lying to you about your indexes.

While moving production database workloads towards cloud-native (Kubernetes) environments has become very popular lately, plenty of users still rely on good old Docker containers. Compared to running PostgreSQL on bare metal, on virtual machines, or via a Kubernetes operator, Docker adds a bit of complexity, especially once you want to go beyond simple pg_dump / pg_restore for backups, upgrades, and disaster recovery.

In a recent Postgres patch authored by Greg Sabino Mullane, Postgres has a new step forward for data integrity: data checksums are now enabled by default.

This appears in the release notes as a fairly minor change but it significantly boosts the defense against one of the sneakiest problems in data management - silent data corruption.

Let’s dive into what this feature is, what the new default means for you, and how it impacts upgrades.

Postgres Ibiza (PGIBZ): An open source conference designed to bring together people with a love for PostgreSQL in Ibiza, a relaxed place for fresh and innovative discussions. An international event run by the nonprofit PostgreSQL España.

This was the first time that the Data Bene team attended the event, and we’re happy to share that it was a very positive experience.
