title: Does postgresql keep track of full table scans it makes?
body: <p>I'd like to do something similar to what's described in <a href="http://www.bestbrains.dk/Blog/2010/03/25/HowToAssertThatYourSQLDoesNotDoFullTableScans.aspx" rel="nofollow noreferrer">http://www.bestbrains.dk/Blog/2010/03/25/HowToAssertThatYourSQLDoesNotDoFullTableScans.aspx</a> but for that I'd need postgres to keep track of any full table scans it does. Is there such a thing for postgres?</p>
