Samay Sharma: Introducing pg_timeseries: Open-source time-series extension for PostgreSQL
We are excited to launch pg_timeseries: a PostgreSQL extension focused on creating a cohesive user experience around the creation, maintenance, and use of time-series tables. You can now use pg_timeseries to create time-series tables, configure the compression and retention of older data, monitor time-series partitions, and run complex time-series analytics functions with a user-friendly syntax.
Stefan Fercot: In-memory disk for PostgreSQL temporary files
Recently, while debugging a performance issue of a CREATE INDEX operation, I was reminded that PostgreSQL might produce temporary files when executing a parallel query, including parallel index creation, because each worker process has its own memory and might need to use disk space for sorting or hash tables.
Thanks to Peter Geoghegan answering this pgsql-admin email thread.
Paolo Melchiorre: Upgrade PostgreSQL from 15 to 16 on Ubuntu 24.04
Howto guide for upgrading PostgreSQL from version 15 to 16 on Ubuntu, after its upgrade from version 23.10 to 24.04 (Noble Numbat).
Radim Marek: Deep Dive into PostgREST - Time Off Manager (Part 2)
Let's recap the first part of "Deep Dive into PostgREST," where we explored the basic functionality to expose and query any table using an API, demonstrated using cURL. All it took was to set up a db-schema and give the db-anon-role some permissions. But unless you are creating the simplest of CRUD applications, this only scratches the surface.

When you send a query to PostgreSQL, it normally would go through stages of query processing and return you the results at the end. These stages are known as:

muhammad ali: Removing Bloat with pg_repack Extension
PostgreSQL's pg_repack extension offers a solution to database maintenance challenges by optimizing table storage without disrupting operations. It tackles issues like bloat and fragmentation efficiently. Learn about its operation, options, and restrictions for effective database management.

Christoph Berg: Git Filters
Nowadays, most Debian packages are maintained in Git repositories, with the majority hosted on Debian's GitLab instance at salsa.debian.org.Debian is running a "vcswatch" service that keeps track of the status of all packaging repositories that have a Vcs-Git (and other VCSes) header set. This status is stored in a PostgreSQL database, which is then utilized by Debian's package maintenance infrastructure for various purposes.
Peter Eisentraut: When to split patches for PostgreSQL
In my previous article on how to submit patches by email for PostgreSQL, I skipped over whether patches should be split up. Let’s discuss that now.
(See the previous article, as well as general Git documentation, for the technical details of how to split up a patch. Here, I’m only talking about why.)

Boy howdy that went fast.
Shane Borden: Use of “pgtt” Extension in Self Managed vs. Cloud Products
There are several benefits to using temp tables in SQL DML operations. Given my long relationship and work on Oracle databases, I am highly familiar with the Oracle style “Global Temporary Tables” and have used them to solve many performance issues when complex joins are involved. That’s why I was excited when Gilles Darold released the extension “pgtt” for PostgreSQL. I was even more excited when Google released the extension for use in the Google CloudSQL for Postgres and AlloyDB for Postgres products.
Deepak Mahto: Conversion Chronicles – Invisible Indexes in Oracle to PostgreSQL Migration.
Any database conversion offers valuable insights into how things work across platforms or how to achieve similar functionality in the target database. Invisible indexes are one such feature that is often requested in PostgreSQL when migrating away, due to their use case of create new or marking existing indexes as invisible for the optimizer.
Making indexes invisible can be beneficial for several use cases, such as:

Radim Marek: Deep Dive into PostgREST - Time Off Manager (Part 1)
The primary motivation behind boringSQL is to explore the robust world of SQL and the PostgreSQL ecosystem, demonstrating how these "boring" tools can cut through the ever-increasing noise and complexity of modern software development. In this series, I'll guide you through building a simple yet fully functional application—a Time Off Manager. The goal of this project is not only to demonstrate practical database/SQL approaches but also to provide a complete, extendable solution that you can immediately build upon.
