I've worked as a support engineer focused on Postgres, and I’ve spent the past two years helping teams debug lock-related issues in production. Lock tooling and resources are not great as of now. They're either standalone, narrow articles, or are overwhelming, or provide little context to beginners.

So I built the resource I wish I had when I was learning.

It:

- explains locks

- provides demos on how they work

- has a tool that shows what blocks what

- outlines troubleshooting strategies with real world examples

- reviews 7 Postgres monitoring tools

Very well written! Definitely learned some new things about PG. Thanks for the resource :)
