postfix does not allow capture of -v output--Why?

Why the *&^*(&^ does postfix not allow its verbose output
ie postfix -v reload
to be redirected to a file. it seems to be putting into stderr, but if I
do postfix -v reload 2>/tmp/p
I get nothing in /tmp/p. What is the use of the -v command since there
is far far to much there to read on the console 9especially as even
piping to less does not work).

Any hints?
