Andrew Atkinson: Big Problems From Big IN lists with Ruby on Rails and PostgreSQL

23. Mai 2025 - 16:30
Introduction

If you’ve created web apps with relational databases and ORMs like Active Record (part of Ruby on Rails), you’ve probably experienced database performance problems after a certain size of data and query volume.

In this post, we’re going to look at a specific type of problematic query pattern that’s somewhat common.

Jeremy Schneider: Collation Torture Test versus Debian

23. Mai 2025 - 7:37

Collation torture test results are finally finished and uploaded for Debian.

https://github.com/ardentperf/glibc-unicode-sorting

The test did not pick up any changes in en_US sort order for either Bullseye or Bookworm

Buster has glibc 2.28 so it shows lots of changes – as expected.

Hubert 'depesz' Lubaczewski: pg_dump speed across versions

22. Mai 2025 - 9:44
Got interested recently in speed of pg_dump. Specifically, if, over the years, it has became faster, and if yes, how much. Couple of years ago I was in position where we needed to run pg_dump, and found some inefficiencies, which got later patched. This was around the version 12. So, how does the situation look … Continue reading "pg_dump speed across versions"

Andrew Atkinson: Short alphanumeric pseudo random identifiers in Postgres

20. Mai 2025 - 18:00
Introduction

In this post, we’ll cover a way to generate short, alphanumeric, pseudo random identifiers using native Postgres tactics.

These identifiers can be used for things like transactions or reservations, where users need to read and share them easily. This approach is an alternative to using long, random generated values like UUID values, which have downsides for usability and performance.
