I think most of nowadays AUCTeX users
wants to have pdf output since Emacs can display it.
For my own, if would use the aggressive approach (2)..

I would just add a message to inform about the configuration because it
is not obvious that we can compile a pstricks document in mode
pdf without changing the package declarations.
