Yeah. The alternatives seem to be:
1. Change a lot of regression tests. This would be a serious PITA,
not so much for the one-time cost as for every time we needed to
back-patch a regression test that includes explain output. -1.
2. Don't display the planning time by default, necessitating a new
PLANNING_TIME ON option. This has backwards compatibility to
recommend it, but not much else.
3. Let COSTS OFF suppress it.
