&gt; &gt; There may be people that don&#x27;t care how their query is actually executed, but I doubt it&#x27;s the common case.<p>&gt; I&#x27;m 100% sure its common.<p>The nice thing about the current state of affairs is that you can first build your queries &#x2F; views until you get the results you need, <i>then</i> look what indices you can add to improve the performance of those queries. And if you get the results you need and find that performance is acceptable, you can just omit (or at least delay) the final step.
