Now that EXPLAIN also outputs a "planning time" measurement, the use of "total" here seems rather confusing: it sounds like it might include the planning time which of course it doesn't. Majority opinion was that "execution time" is a better label, so we'll call it that. This should be noted as a backwards incompatibility for tools that examine EXPLAIN ANALYZE output. In passing, I failed to resist the temptation to do a little editing on the materialized-view example affected by this change.
