That does seem cleaner than parsing the EXPLAIN output as we're
playing with right now. I've been assuming that these experiments
are merely proof of concept and prototypes for how we'd like it to
work.

What about making both ways work? EXPLAIN would format the output
the way it currently looks, and SELECT * FROM explain(...) would
return a resultset.
