Christoph Berg: Git Filters

Neues vom PostgreSQL Planet - 14. Mai 2024 - 9:13

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

Neues vom PostgreSQL Planet - 14. Mai 2024 - 6:00

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.)

Shane Borden: Use of “pgtt” Extension in Self Managed vs. Cloud Products

Neues vom PostgreSQL Planet - 13. Mai 2024 - 20:40

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.

Neues vom PostgreSQL Planet - 13. Mai 2024 - 17:22
Introduction – Invisible or Hidden Index.

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)

Neues vom PostgreSQL Planet - 11. Mai 2024 - 2:00

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.

Shaun M. Thomas: PG Phriday: On the Move

Neues vom PostgreSQL Planet - 10. Mai 2024 - 22:13

Sometimes when we have an existing database and schema full of tables, there comes a time when we need to perform a migration. Maybe it’s because we want to move to or from a cloud service. Perhaps we have a small database and want to do a quick version upgrade via dump / restore. Whatever the reason, we may decide to clean up some technical debt while we’re making the transition.
