Hi experts!

I read this nice article about Understanding EXPLAIN [1] weeks ago that
opened my mind about the tool, but it seems no enough to explain a lot of
plans that I see in this list.

I often read responses to a plan that are not covered by the article.

I need/want to know EXPLAIN better.

Can you kindly advise me a good reading about advanced EXPLAIN?

Thank you!
