PostgreSQL’s JSONB data type gives you the flexibility of a document store while keeping all the relational superpowers you already know. But the truth is simple: most developers struggle with JSONB purely because they forget the syntax. This guide is the refresher I wish someone handed me years ago!

PostgreSQL’s JSONB type is incredibly powerful. It’s flexible, fast, and lets developers store semi-structured data without spinning up a separate document store. But here’s the truth: most JSONB performance problems come from developers treating JSONB like a magic box instead of a real data type with real indexing rules.

PostgreSQL locking feels scary — mostly because the documentation lists 15 different lock modes, half of which sound like they were named during a caffeine-fueled meeting. But here’s the truth: you only need to understand a few key concepts to debug almost every lock issue you’ll ever encounter.

PostgreSQL gives you a huge toolbox of data types, which is great — until you accidentally pick the wrong one and end up fighting performance issues, storage problems, or subtle bugs that show up months later. In this article, we’ll go over the four data type pairs developers misuse the most, and I’ll show you the simple rules that will keep your schemas clean and your data correct.

PostgreSQL offers multiple index types, each optimized for different query patterns and data shapes. Understanding which one to use is one of the highest-ROI skills in database engineering.

Indexing is one of the most misunderstood areas of PostgreSQL performance tuning. Developers often assume that “more indexes = faster queries.” This article explains when multiple single-column indexes make sense, when a multi-column index is better, and how PostgreSQL decides.
I’ve spent over 20 years optimizing databases and designing rock-solid data systems. Now I’m sharing what I’ve learned to help others build faster, smarter, and more reliable platforms.
