The topic of this month’s PGSQL Phriday #014 community blogging event—where people from different companies and different countries all blog about the same topic on the same day—is PostgreSQL Events. Big thanks to Pavlo Golub for organizing this month's PGSQL Phriday.

Deciding what event to blog about was a bit of a challenge—there are so many Postgres events worth shining a light on! Top of mind at this moment are PGConf EU which will happen in Prague in December—and the Path To Citus Con monthly podcast that I co-host for developers who love Postgres.

So what Postgres event did I choose for this PGSQL Phriday post?

I thought y’all might appreciate this “Illustrated Guide” to my Postgres experience at the PASS Data Community Summit 2023 which happened in Seattle, WA on November 14-17. Let’s dive in.

Introducing Path To Citus Con, a podcast for developers who love Postgres. Why? Because sometimes, something you build gets bigger than you thought it would. The monthly podcast Path To Citus Con as originally meant to be a “pre-event” to build excitement and give a hands-on experience for people who would be attending Citus Con: An Event for Postgres. The audience would get a chance to talk to speakers for the conference and hear a deep dive conversation.

It’s now its own monthly podcast with guests from around the world. Guests have been deep in the world of databases and the Citus database extension to Postgres, and also people in the Postgres community and technology more generally. It’s the human side of open source, PostgreSQL, and the many PG extensions (including Citus.)

In this blog post, you’ll learn about what Path To Citus Con is, how you can participate, listen, and read each episode, and about episodes like “Working in public on open source,” “Why giving talks at Postgres conferences matters,” and more (details below.)

A developer friend of mine prefers to read about what to expect at upcoming events in the narrative form of a blog, rather than having to click in and out of different abstracts on a schedule page.

So this ultimate guide post is my gift to those of you who want to know more about the 37 talks that will be presented at this year’s 2nd annual Citus Con: An Event for Postgres 2023—and who want to read about it in blog post form.

And yes, Citus Con is virtual again this year! This means you can watch all the livestream & on-demand talks from the comfort of your very own desk—and chit-chat in the virtual hallway track on the #cituscon channel on Discord.

[Update in May 2023]: It's a wrap! The categories in this ultimate guide will help you find the talks which are most useful to you and your work/interests. Or you can jump straight to the playlist of all 37 Citus Con 2023 talks on YouTube.

So what’s on the schedule at Citus Con: An Event for Postgres 2023, exactly? Be sure to check out both tabs on the Schedule page, both the Live Sessions & the On-Demand Sessions tabs, to learn about the:

For those of you looking to give a talk at a Postgres conference, some good news: the CFP is open for Citus Con: An Event for Postgres 2023. Citus Con is a free and virtual developer event happening next April, hosted by the Postgres and Citus teams at Microsoft.

Carpe diem, as the CFP will close on Feb 5, 2023 at 11:59pm PST.

Videos of all of the Citus Con talks will be published online for the world to see, including on YouTube—so the reach of your talk is not limited to the day of the event.

Because it’s a virtual event, you won’t need to travel to give your talk. And you don’t need to worry about the process of recording your talk: the organizers take care of the video recording and production—all you need is a decent webcam and microphone. You can see from the playlist of last year’s Citus Con talks that the production values of the videos are quite good.

Debugging Postgres autovacuum problems: 13 tips

Written byBy Samay Sharma | July 28, 2022Jul 28, 2022

If you've been running PostgreSQL for a while, you've heard about autovacuum. Yes, autovacuum, the thing which everybody asks you not to turn off, which is supposed to keep your database clean and reduce bloat automatically.

And yet—imagine this: one fine day, you see that your database size is larger than you expect, the I/O load on your database has increased, and things have slowed down without much change in workload. You begin looking into what might have happened. You run the excellent Postgres bloat query and you notice you have a lot of bloat. So you run the VACUUM command manually to clear the bloat in your Postgres database. Good!

But then you have to address the elephant in the room: why didn't Postgres autovacuum clean up the bloat in the first place...? Does the above story sound familiar? Well, you are not alone. 😊

One of the good things with a virtual event like Citus Con is that you have a lot of flexibility about where and when to watch the talks. From your home office, or a café, or the beach—or even the car, while you wait to pick up your kids. As long as you have an internet connection, you’re in.

But you still need to figure out which talks and livestreams you want to watch when the event goes live on Tuesday, April 12. To help you out, we’ve created this guide to Citus Con: An Event for Postgres. And just for kicks I’m calling it the “Ultimate Guide” to CitusCon. (Ha! Since this is a first time event maybe it will be the only guide to Citus Con. Therefore definitely “ultimate”.)

In working on this event—I’m a co-chair along with Teresa Giacomini, also head of the talk selection team—I realized I had “tagged and categorized” each and every talk both in my head and on a spreadsheet. So that’s what this blog post will give you… a framework for knowing which talks are in which categories.

Of course, if you want to see the abstracts for all the talks, just pop over to the Schedule & Sessions page for Citus Con.

When you find yourself answering the same questions again and again, it’s a good idea to blog about it. Which is why this post about Citus Con: An Event for Postgres exists: to answer your questions, and share the news about this first-ever, inaugural event.

Citus Con: An Event for Postgres is a free and virtual developer event happening in April 2022, organized by the Postgres and Citus team here at Microsoft. Speakers will come from different parts of the Postgres ecosystem, including Postgres users, Citus open source users, Azure Database for PostgreSQL customers, and developers/experts in PostgreSQL and Postgres extensions, like Citus.

The Call for Proposals (CFP) for Citus Con is open until Feb 6th. Whether this will be your 1000th conference talk or your very 1st, we’d love to see what Postgres experiences you have to share.

If you’ve never done it before, you might be daunted by the idea of giving a conference talk. You know: the work involved, the butterflies, how to make it a good talk and not a boring one, the people who might judge you… And perhaps the hardest bit: choosing a topic others will find interesting.

[Updated for 2024]: For the 3rd year in a row, I’m the chair of the talk selection team for a free and virtual developer conference that is now called POSETTE: An Event for Postgres, formerly called Citus Con. I’ve also served on talk selection committees for PgDaySF 2020 and PGDay Chicago 2024. Wearing my talk selection team hat, as I reached out to spread the word about open CFPs such as the CFP for POSETTE, people would sometimes ask:

Why give a talk at a Postgres conference?

This post will walk you through the ways you, your team, your project—and especially the Postgres community—can benefit from a talk you give.
