The problem I'm having with the way it stands now is that one would
reasonably expect that "Total time" is the total of all times counted
by EXPLAIN, including main plan execution time, trigger firing time,
and now planning time. Since it is not, any longer, a total, I think
renaming it would be a good idea. I'm not wedded to "execution time"
in particular, but I don't like "total".
