Neues vom PostgreSQL Planet

PostgreSQL is highly suitable for powering critical applications in all industries. However, to run critical applications, there are key requirements which are absolutely needed: High-Availability and automatic failover. 

This document explains which options are available and which problems one can solve with PostgreSQL. We have listed the most common setups and some of the most common recommendations. 

In Part 1 of this series, we loaded our documentation into PostgreSQL using the pgEdge Document Loader. Our documents are sitting in the database as clean Markdown content, ready for the next step: turning them into something an LLM can search through semantically.In this post, we'll use pgEdge Vectorizer to chunk those documents and generate vector embeddings.

If you've ever had to scrub significantly large tables—whether updating older records or deleting expired ones—you know the pain of trying to do it efficiently without locking the entire table. One common trick is to iterate over the ctid (the physical location of the tuple) to process the table in chunks. Until now, this was strictly a single-threaded affair. But with the latest commit to

On Nov. 20, the day after GIS Day, Elizabeth Christensen and I hosted the 7th annual PostGIS Day, a celebration of the Little Spatial Database That Could. Brought to you this year by Snowflake, the event featured an amazing collection of speakers from around the globe — from India to Africa, Europe to North America.

Last week, I read The Register’s coverage of MongoDB CEO Chirantan “CJ” Desai telling analysts that a “super-high growth AI company … switched from PostgreSQL to MongoDB because PostgreSQL could not just scale.” (The Register)

I believe you can show the value of your own technology without tearing down another. That is really what this post is about.

Bruce Momjian spoke at the PG Armenia Community Meetup, organised by Emma Saroyan on December 4 2025.

If you need to migrate quickly from Oracle to PostgreSQL without worrying about type conversions or other Oracle packages that require modifications to be PostgreSQL-compatible, a useful solution is IvorySQL!

I have attended over one hundred Postgres meetups over the years. The usual format is: food with individual discussion, lecture with group questions, and finally more individual discussion. I just spoke at an Armenia PostgreSQL User Group meetup and the event organizer Emma Saroyan did something different — she did a group mobile phone quiz after my lecture.

In the past there have been many discussions about using UUID as a primary key in PostgreSQL. For some applications, even a BIGINT column does not have sufficient range: it is a signed 8‑byte integer with range −9,223,372,036,854,775,808 to +9,223,372,036,854,775,807. Although these values look big enough, if we think about web services that collect billions or more records daily, this number becomes less impressive.

The PostgreSQL Hacking Workshop will be taking a well-earned Christmas break in December of 2025. The future of the workshop is a little bit unclear, because I'm continuing to have a bit of trouble finding enough good talks online to justify doing one per month: the best source of talks for the event is pgconf.dev, but not all of those talks are about hacking on PostgreSQL, and not all of those that are about hacking are equally interesting to potential attendees.

Earlier this year we started a program (“Developer U”) to help colleagues who show promise for PostgreSQL Development to become contributors. Meet Bryan Green, working on the Platform Operations team at EDB, who just enjoys understanding how things work at the lowest levels.
