I should add, in my experience optimising queries, a time breakdown is generally the first step of many. Flamegraphs are great at telling you where in 1,000 invocations your time is spent, but your execution plan only has ~20 nodes max, and the percentages do that job well enough. At that point, you want to know why it's slow, and a flamegraph representation of those percentages won't help you with that.
