Jan Wieremjewicz: The PG_TDE Extension Is Now Ready for Production

30. Juni 2025 - 18:00
Lately, it feels like every time I go to a technical conference, someone is talking about how great PostgreSQL is. I’d think it’s just me noticing, but the rankings and surveys say otherwise. PostgreSQL is simply very popular. From old-school bare metal setups to VMs, containers, and fully managed cloud databases, PostgreSQL keeps gaining ground. And […]

PostgreSQL Person of the Week Interview with Samed YILDIRIM: I’m originally from Turkey. The last city I lived in Turkey was Istanbul. I am now living in Riga, Latvia for more than 5 years already.

Ian Barwick: PgPedia Week, 2025-06-29

30. Juni 2025 - 12:50

Housekeeping announcements:

this website's PostgreSQL installation is now on version 17 ( insert champagne emoji here ) the search function now works properly with non-ASCII characters ( there was an embarrassing oversight which went unnoticed until someone kindly pointed it out ) PostgreSQL 18 changes this week

This week there have been a couple of renamings:

Tomas Vondra: How often is the query plan optimal?

30. Juni 2025 - 12:00

The basic promise of a query optimizer is that it picks the “optimal” query plan. But there’s a catch - the plan selection relies on cost estimates, calculated from selectivity estimates and cost of basic resources (I/O, CPU, …). So the question is, how often do we actually pick the “fastest” plan? And the truth is we actually make mistakes quite often.

Andreas Scherbaum: Performance Test for Percona Transparent Data Encryption (TDE)

30. Juni 2025 - 0:00
This blog posting compares the performance of the pg_tde by Percona extension for PostgreSQL with the performance of an unmodified PostgreSQL. The pg_tde by Percona extension provides encryption for both data pages on disk as well as WAL files on disk - Encryption at Rest. The extension is currently in the rc stage (release candidate). This test does not compare pg_tde by Percona to other products. It tests the extension performance and compares with unmodified PostgreSQL, and shows how much overhead it is to encrypt data at rest, and encrypt WAL.

PgPedia Week has been delayed this week due to malaise and other personal circumstances.

semab tariq: Choosing the Right Barman Backup Type and Mode for Your PostgreSQL Highly Available Cluster

27. Juni 2025 - 12:55

When running a PostgreSQL database in a High Availability (HA) cluster, it’s easy to assume that having multiple nodes means your data is safe. But HA is not a replacement for backups. If someone accidentally deletes important data or runs a wrong update query, that change will quickly spread to all nodes in the cluster. Without proper safeguards, that data is gone everywhere. In these cases, only a backup can help you restore what was lost.

Dave Stokes: Entity Relationship Maps

25. Juni 2025 - 15:26

    Even the most experienced database professionals are known to feel a little anxious when peering into an unfamiliar database. Hopefully, they inspect to see how the data is normalized and how the various tables are combined to answer complex queries.  Entity Relationship Maps (ERM) provide a visual overview of how tables are related and can document the structure of the data.

Gabriele Bartolini: CNPG Recipe 20 – Finer Control of Postgres Clusters with Readiness Probes

25. Juni 2025 - 8:04

Explore the new readiness probe introduced in CloudNativePG 1.26, which advances Kubernetes-native lifecycle management for PostgreSQL. Building on the improved probing infrastructure discussed in my previous article, this piece focuses on how readiness probes ensure that only fully synchronised and healthy instances—particularly replicas—are eligible to serve traffic or be promoted to primary.

Magnus Hagander: PGConf.EU 2025 - Registration opened

24. Juni 2025 - 16:37

The registration for PGConf.EU 2025, which will take place on 21-24 October in Riga, is now open.

We have a limited number of tickets available for purchase with the discount code EARLYBIRD.

This year, the first day of training sessions has been replaced with a Community Events Day. This day has a more limited space, and can be booked as part of the conference registration process or added later, as long as seats last.

Radim Marek: Beyond the Basics of Logical Replication

24. Juni 2025 - 9:10

With First Steps with Logical Replication we set up a basic working replication between a publisher and a subscriber and were introduced to the fundamental concepts. In this article, we're going to expand on the practical aspects of logical replication operational management, monitoring, and dive deep into the foundations of logical decoding.

Cornelia Biacsics: Contributions for the week of 2025-06-09 (Week 24)

24. Juni 2025 - 8:36

On June, 9th, Andrzej Nowicki held a talk about “From Queries to Pints: Building a Beer Recommendation System with pgvector” at the Malmö PostgreSQL User Group.

On June, 3rd the 5. PostgreSQL User Group NRW MeetUp took place in Germany.

Peter Eisentraut: Waiting for SQL:202y: Vectors

24. Juni 2025 - 6:00

It’s been a while since SQL:2023 was published, and work on the SQL standard continues. Nowadays, everyone in the database field wants vectors, and SQL now has them, too.

(I’m using the term “SQL:202y” for “the next SQL standard after SQL:2023”. I took this naming convention from the C standard, but it’s not an official term for the SQL standard. The current schedule suggests a new release in 2028, but we’ll see.)

semab tariq: Which PostgreSQL HA Solution Fits Your Needs: Pgpool or Patroni?

20. Juni 2025 - 13:13

When designing a highly available PostgreSQL cluster, two popular tools often come into the conversation: Pgpool-II and Patroni. Both are widely used in production environments, offer solid performance, and aim to improve resilience and reduce downtime; however, they take different approaches to achieving this goal.

Alexander Korotkov: The differences between OrioleDB and Neon

20. Juni 2025 - 2:00

In a recent Hacker News discussion, there was some confusion about the differences between OrioleDB and Neon. Both look alike at first glance. Both promise a "next‑gen Postgres". Both have support for cloud‑native storage.

This post explains how the two projects differ in practice. And importantly, OrioleDB is more than an undo log for PostgreSQL.

Robert Haas: PostgreSQL Hacking + Patch Review Workshops for July 2025

19. Juni 2025 - 20:01
Next month, I'll be hosting 2 or 3 discussions of Tomas Vondra's talk, Fast-path locking improvements in PG18, given at 2025.pgconf.dev (talk description here). If you're interested in joining us, please sign up using this form and I will send you an invite to one of the sessions.

Jan Wieremjewicz: PostgreSQL active-active replication, do you really need it?

18. Juni 2025 - 2:00
PostgreSQL active-active replication, do you really need it? Before we start, what is active-active?

Active-active, also referred to as multi-primary, is a setup where multiple database nodes can accept writes at the same time and propagate those changes to the others. In comparison, regular streaming replication in PostgreSQL allows only one node (the primary) to accept writes. All other nodes (replicas) are read-only and follow changes.

In an active-active setup:
