Citus Blog

A year ago we renamed the Talking Postgres podcast—and just published our 29th episode. Since it’s a monthly thing, that means 13 new conversations in the past year. So this feels like a good moment to pause, reflect, and share a few highlights.

If you’re already a listener, this post might help you find an episode you missed. If you’re new to the podcast, think of this as a sampler: a few favorite quotes, some backstory, and quick-hit summaries of each episode from the past year.

What is the Talking Postgres podcast? It's a long-form conversation—usually an hour, often more—with people in the Postgres world. We talk about what they do with Postgres, why they do it, and how they got started. (I’m a bit obsessed with origin stories.)

The show isn’t about features or how-to’s. It’s not about speeds and feeds. And it’s definitely not trying to sell you anything. It’s about the people behind Postgres—and what we can learn from each other.

The Citus 13.0 release is out and includes PostgreSQL 17.2 support! We know you’ve been waiting, and we’ve been hard at work adding features we believe will take your experience to the next level, focusing on bringing the Postgres 17 exciting improvements to you at distributed scale.

The Citus database is an open-source extension of Postgres that brings the power of Postgres to any scale, from a single node to a distributed database cluster. Since Citus is an extension, using Citus means you're also using Postgres, giving you direct access to the Postgres features. And the latest of such features came with Postgres 17 release! In addition, Citus 13 will be made available on the elastic clusters (preview) feature on Azure Database for PostgreSQL - Flexible Server, along with PostgreSQL 17 support, in the near future.

PostgreSQL 17 highlights include performance improvements in query execution for indexes, a revamped memory management system for vacuum, new monitoring and analysis features, expanded functionality for managing data in partitions, optimizer improvements, and enhancements for high-concurrency workloads. PostgreSQL 17 also expands on SQL syntax that benefits both new workloads and mission-critical systems, such as the addition of the SQL/JSON JSON_TABLE() command for developers, and the expansion of the MERGE command. For those of you who are interested in upgrading to Postgres 17 and scaling these new features of Postgres: you can upgrade to Citus 13.0!

Along with Postgres 17 support, Citus 13.0 also fixes important bugs, and we are happy to say that we had many community contributions here as well. These bugfixes focus on data integrity and correctness, crash and fault tolerance, and cluster management, all of which are critical for ensuring reliable operations and user confidence in a distributed PostgreSQL environment.

Let's take a closer look at what's new in Citus 13.0:

Some of you have been asking for advice about what to submit to the CFP for POSETTE: An Event for Postgres 2025. So this post aims to give you ideas that might help you submit a talk proposal (or 2, or 3) before the upcoming CFP deadline.

If you’re not yet familiar with this conference, POSETTE: An Event for Postgres 2025 is a free & virtual developer event now in its 4th year, organized by the Postgres team at Microsoft.

I love the virtual aspect of POSETTE because the conference talks are so accessible—for both speakers and attendees. If you’re a speaker, you don’t need travel budget $$—and you don’t have to leave home. Also, the talk you’ve poured all that energy into is not limited to the people in the room, and has the potential to reach so many more people. If you’re an attendee, well, all you need is an internet connection.

The CFP for POSETTE: An Event for Postgres will be open until Sunday Feb 9th at 11:59pm PST. So as of the publication date of this blog post, you still have time to submit a CFP proposal (or 2, or 3, or 4)—and to remind your Postgres teammates and friends of the speaking opportunity.
