Our waitlist has now been activated, as the conference is close to selling out.
We have seats left, and may get a couple of extra ones if outstanding invoices are not paid on time. However, we have no ability to further extend the total number of seats (as they are limited by the venue). So if you want a chance to get one of these seats, make sure you sign up as soon as possible! The waitlist ensures fair allocation of the remaining seats.
Gabriele Bartolini: Create a PostGIS Database in Kubernetes with CloudNativePG and Improve the Spatial Experience
Compared to PostgreSQL alone, TimescaleDB can dramatically improve query performance by 1000x or more, reduce storage utilization by 90%, and provide features essential for time-series and analytical applications. Some of these features even benefit non-time-series data–increasing query performance just by loading the extension.
Postgres is an awesome database for a lot of reasons, put simply it's a really feature rich, powerful, and reliable database. One of those rich areas is the many built-in functions in Postgres.
Let's take a look at a few of my favorites.Date functions
First, let's start with one of the most simple built-in ones but when doing things with time is quite handy.
Want to know what time it is according to your database?
With pgBackRest 2.41 just released, a new feature called backup annotations is now available. Let’s see in this blog post what this is about.Backup annotations
This new feature adds an --annotation option to the backup command. We can now attach informative key/value pairs to the backup and the option may be used multiple times to attach multiple annotations.
This topic describes how you can detect and solve PostgreSQL checkpoints ratio issuesWhat happened?
To detect checkpoints ratio issues, and have an ability to look in some historical metrics of this – you must have some kind of monitoring solution. Today, there is a rich selection of monitoring solutions – you can use any you already have, or install another one. Here we will discuss samples based on Awide management and monitoring solution.
Sequences are a core feature of SQL. However, some users are tempted to implement sequences to generate invoices. That’s dangerous and should be avoided. The core question is: Why? What’s the problem with using database-side sequences to put unique invoice numbers to send to clients? Let’s dive in and find out.
I’m excited to announce that the translation of Part III of the “PostgreSQL 14 Internals” book is finished. This part is about a diverse world of locks, which includes a variety of heavyweight locks used for all kinds of purposes, several types of locks on memory structures, row locks which are not exactly locks, and even predicate locks which are not locks at all.
A new release of the PostgreSQL virtual environment manager.pgenv 1.3.2 is out!
Today we released version 1.3.2 of pgenv, the binary manager for PostgreSQL.
This release fixes a quite subtle bug in the handling of the configuration that prevented custom settings to be correctly loaded back into the running system. Users are encouraged to upgrade as soon as possible.
Citus is a distributed database that is built entirely as an open source PostgreSQL extension. In fact, you can install it in your PostgreSQL server without changing any PostgreSQL functionality. Citus simply gives PostgreSQL additional superpowers.
At Crunchy we talk a lot about memory, shared buffers, and cache hit ratios. Even our new playground tutorials can help users learn about memory usage. The gist of many of those conversations is that you want to have most of your frequently accessed data in the memory pool closest to the database, the shared buffer cache.
In my previous post I wrote about how to configure and manage virtual IP for Pgpool-II on AWS.
As I mentioned in my previous post, there are four methods to assign the virtual IP on AWS:

Psycopg, the PostgreSQL database adapter for Python, recently added support for libpq pipeline mode thus bringing significant performance boost, especially when network latency is important. In this article, we’ll briefly describe how it works from users’ perspective and under the hood while also providing a few implementation details.
Not quite a year ago, I had the opportunity to give a keynote address at PGConf NYC 2021 as part of Timescale’s sponsorship. Thankfully the leadership at Timescale supported me addressing the topic of community and how, particularly in light of the upward trend of PostgreSQL adoption, investing in the growing community can help everyone involved.
