Neues vom PostgreSQL Planet

With PostgreSQL 18 introducing built-in OAuth 2.0 and OpenID Connect (OIDC) authentication, tools like pg_oidc_validator have become an essential part of the ecosystem by enabling server-side verification of OIDC tokens directly inside PostgreSQL. If you’re new to the topic, make sure to read our earlier posts explaining the underlying concepts and the need for external validators:

Everyone wants high availability, and that’s completely understandable. When an app goes down, users get frustrated, business stops, and pressure builds.

But here’s the challenge: high availability often feels like a big monster. Many people think, If I need to set up high availability, I must master every tool involved. And there’s another common belief too: Open-source tools are not enough for real HA, so I must buy paid tools.

A useful new feature was introduced on 11 December 2025: Allow expiration of the oldest full backup regardless of current retention. Details are available in commit bf2b276.

One of the principal and most powerful components of the pgEdge Agentic AI Toolkit is the pgEdge Postgres MCP Server. In just over a year MCP (Model Context Protocol), initially developed by Anthropic, has become the standard way to connect LLMs to external data sources and tools.

We are delighted today to be announcing the beta release of our pgEdge Agentic AI Toolkit for Postgres.  We’ve had the benefit of collaborating on real-world Postgres-based AI applications the past two years with a number of leading customers, and this product announcement is the outgrowth of this learning.We listened to customers as they refined their AI strategies in response to the rapid evolution of LLMs, Agentic AI and integration technologies such as the Model Context Protocol (MCP), and as we did so a few things sto

Most major Linux distributions have upgraded to the GNU C library version 2.28 or later. Therefore, there is a growing awareness that an operating system upgrade can lead to index corruption. However, rebuilding all your indexes can slow down the upgrade process considerably. In this article, I want to discuss how you can avoid rebuilding more indexes than necessary.

A Journey Through PostgreSQL Events

• Introduction
• Community recognition (transparency, inclusivity, organisational balance)
• If I organise a PostgreSQL event — does it have to be recognised?
• Are community-recognised events better than those that aren’t?
• Conferences — a quick flyover (pgDays, pgConfs, FOSDEM, PGConf.dev etc.)
• PostgreSQL User Groups / meet-ups
• Key takeaways
• Which PostgreSQL event to attend?
