+1 for the machine readable explain.
FWIW, I have an early patch for phpPgAdmin about a graphical explain.
IIRC when I wrote it, I told myself the parser might actually be broken
with multi-level sub-queries or something. But I ended with the same
parsing code than pgAdmin anyway.
About the format, JSON would be the best here, as it is a one function
call in PHP to retrieve an associative array from the JSON code.
