Really solid approach to organizing query optimization knwoledge. The A-to-Z structure makes it way easier to remember specific techniques under pressure, especially during incidents when nobody's got time to dig through 50-page docs. One thing worth noting though is that EXPLAIN ANALYZE can be deceiving with cached data, so running it cold a few times helps spot the actual bottleneck behavior.
Totally agree during high pressure incidents, we forget easily basic stuff.
And yes, great point about EXPLAIN ANALYZE being tricky with warm caches. I usually force a few cold runs or drop the cache to see the real bottlenecks.

Thanks!

Appreciate you highlighting that.
