PSequel, a PostgreSQL GUI Tool for macOS
PostgreSQL GUI tool for macOS PSequel provides a clean and simple interface for you to perform common PostgreSQL tasks quickly. FAQWhy yet another PostgreSQL GUI client? Why not just pgAdmin?Well, pgAdmin is great for its feature-richness. However, I found its UI is clumsy and complicated. I know there is a list of PostgreSQL GUI Tools.

A Visual Explanation of SQL Joins
I thought Ligaya Turmelle's post on SQL joins was a great primer for novice developers.
