Postgres Encryption: The Available Options — When it comes to encryption, you’re on your own with vanilla Postgres out of the box, but various layers of data security are available from those provided by your hardware to Postgres extensions (e.g. pgsodium) or app-level defences. This post provides a brief overview, and also provoked an extensive Hacker News discussion on the topic.

Writing a Storage Engine for Postgres: An In-Memory Table Access Method — Phil summed up this tour de force post best: “I’ve been working this week to understand Postgres Table Access Methods for alternative storage engines. Especially challenging because the documentation is pretty sparse and few minimal implementations exist. I wrote up my approach!”

Timescale Introduces Dynamic PostgreSQL — Boldly claiming to be ‘the next evolution of the database’, this is ultimately an innovation upon Timescale’s Postgres platform, but an interesting one nonetheless. Dynamic PostgreSQL provides a consistent baseline of performance but can instantaneously scale compute within a pre-defined range – they call this model “buy the base, rent the peak.”

🤯  SQL Scoping is Surprisingly Subtle and Semantic — Justin presents us with a very simple set of SQL queries and asks us to predict what they’ll return. I’d be surprised if you got them right. A fun look at some potentially unintuitive (but standardized) SQL behavior.

DoltgreSQL: Postgres-Compatible Database with Version Control Concepts — Dolt is a long standing Go-powered database providing a ‘git for data’ type experience with branching, cloning, merging and more, but using the MySQL wire protocol. DoltgreSQL offers the same but over the Postgres wire protocol - hurrah!

PGLoader: A Data Loading Tool for Migrating to Postgres — A long-standing data loading tool that supports parallelism and can load in data that may be partially erroneous but without stopping (as \copy might). Recently referenced in this MySQL to Postgres migration story.
