If it’s just a terminology issue, what about EXPLAIN (*); already a precedent with SELECT * to mean “everything”. (MAX? LIKE_I’M_5?) Let the bikeshedding begin!

In any case, I think a shorthand for “give me the most possible detail without me having to lookup/type/remember the options” is a good tool.
