The tool for highlighting EXPLAIN output is provided on http://explain.depesz.com/ (as mentioned in a later slide). It's commonly used when asking for help and discussing queries on #postgresql on Freenode.

Can also warmly recommend the EXPLAIN visualizations generated by pgAdmin: http://www.pgadmin.org/

See an (simple) example here: http://www.pgadmin.org/images/screenshots/pgadmin3_macosx.pn...

And I haven't completely finished my explanation of it! http://jimkeener.com/posts/explain-pg

I love EXPLAIN, it's such an amazing tool for figuring out how to get a query to run faster. It's much more detailed than MySQL's and often one of the reasons I list when people ask if they should checkout/switch to pg (which you should!)

Another EXPLAIN documentation, probably easier to read since it's a PDF and not a slideshow: http://www.dalibo.org/_media/understanding_explain.pdf

Thanks for this. I really like postgres community.They are vibrant and you will almost always learn one thing or the other from them.

Where is the video for this?

Nice one. Is there an offline/downloadable version available?

You could grab the site (or just individual files) from github: https://github.com/jberkus/jberkus.github.io

The README on https://github.com/jberkus/jberkus.github.io/tree/master/exp... has instructions to get it running locally

I couldn't find either.
