Neues vom PostgreSQL Planet

In Part 1 we loaded our documentation into PostgreSQL. In Part 2 we chunked those documents and generated vector embeddings. Now it's time to put it all together with an API that your applications can use.

If you need to transition easily 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!

There’s nothing simple about simplification! It is very common to want to slim down the size of geometries, and there are lots of different approaches to the problem.

We will explore different methods starting with ST_Letters for this rendering of the letter “a”.

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.
