While I like the general idea, I have to admit that I don't particularly
like the format and I'm not sure why it makes sense to have this as part
of 'explain'? Why not do a 'show all;' ahead of the explain?

A bit more understanding about why you find it particularly useful (your
specific use-case for it) would be helpful. Also, may I suggest that
you look at http://commitfest.postgresql.org as you'll be asked to post
any patches you wish to submit there for review and consideration.
Thanks!
