Do not do that...
For this reason:
* Any serious database administrator will read the documentation and
take the time to configure the system for such a setup. The setup will
be specific to his/her demands, competing with the backup window
perhaps.
* Any new user, developers and hobbiests don't need such things to
increase performance a little and several most likely turn off their
systems during the night. This effectively results in people that get
serious problems using postgresql, because vacuum never runs. You know
who they will blame for it.

Just my opinion...

I agree.  There is nothing very special about that particular time window.
   The default IMO should be to run all the time, or not at all.
