Looks good and useful for me, too.
We need to adjust a bit more documentation. The patch changes all of
EXPLAIN ANALYZE outputs. When I grep'ed the docs with "loops=",
EXPLAIN ANALYZE is also used in perform.sgml and auto-explain.sgml
in addition to explain.sgml.
It's good to have documentation about "nfiltered" parameter. The best
place would be around the descriptions of "loops" in "Using EXPLAIN" page:
http://developer.postgresql.org/pgdocs/postgres/using-explain.html
