Hi,

For benchmarking the parser I added the above options (dim suggested this on 
irc) which proved to be rather useful for me.
I added the additional rewrite option because the overhead of copying the tree 
around makes the profile significantly less expressive.
I would also like an option which would only do the actual parsing instead of 
parse + parse analyse but that seemed a tad more complicated...

Is anybody else interested in such EXPLAIN options?

Andres
