Kaarel Moppel: Striping Postgres data volumes - a free lunch?

23. April 2025 - 23:00
A small follow up on my previous post on various Postgres scale-up avenues in my preferred order. The post received quite a bit of interest - meaning people at least still “wish” performant databases :) And - the ones who are willing to put in a bit of effort with...

Ernst-Georg Schmid: TRAKTOR revisited

22. April 2025 - 16:52

Working on TRAKTOR again. The good news is, it still works with PostgreSQL 17.x and I have completely replaced psycopg2 with pg8000 to remove all native dependencies. The bad news is, if you don't want to run the arbiter as superuser it's a complicated dance of permissions, some of which can only be GRANTed by a superuser, and I have to find a way to automate this as far as possible.

Andrei Lepikhov: On expressions' reordering in Postgres

22. April 2025 - 13:08

Today, I would like to discuss additional techniques to speed up query execution. Specifically, I will focus on rearranging conditions in filter expressions, JOINs, HAVING clauses, and similar constructs. The main idea is that if you encounter a negative result in one condition within a series of expressions connected by the AND operator, or a positive result in one of the conditions linked by the OR operator, you can avoid evaluating the remaining conditions. This can save computing resources.

Ibrar Ahmed: 8 Steps to Proactively Handle PostgreSQL Database Disaster Recovery

22. April 2025 - 8:13

When disaster strikes, whether a natural disaster or a technical event, its impact on your network, database, and end-users can cause both costly downtime and data corruption. Data corruption, whether sparked by hardware failures like dying disks or faulty RAM, software glitches such as operating system bugs, or human missteps like accidental overwrites, is a terrifying prospect for any administrator. Yet, it’s not a death sentence.Your PostgreSQL database is typically a dependable cornerstone of your operations.

Laurenz Albe: Type alignment and padding bytes: how to not waste space in PostgreSQL tables

Saving storage space should not be your first objective in a PostgreSQL database. Very often, the desire to conserve space aggressively comes at the expense of performance. But there is also no reason to needlessly waste space. Therefore, it is a good idea to be familiar with the concepts of data type alignment and padding bytes in PostgreSQL.

David Wheeler: Fix Postgres <code>strchrnul</code> Compile Error on macOS 15.4

16. April 2025 - 21:03

Just a quick note to users of pgenv and anyone else who compiles Postgres on macOS. In macOS 15.4, Apple introduced a new API, strchrnul, which is common from other platforms. As a result attempting to compile Postgres on 15.4 and later will lead to this error:

Louise Grandjonc: Hacking the Postgres Statistics Tables for Faster Queries

16. April 2025 - 15:00

Postgres does a great job of making queries really efficient. By gathering data in internal statistics tables, Postgres estimates before a query is run lots of things - like will an index scan be better than a sequential scan. How to pull data for the WHERE statement.
