Changing resolution is not possible on the fly. PS is a programming
language similar to FORTH (it uses IPN). You can do anything you want
with it after you understand the language and the fact that what is
being rendered may not be scalable sometimes. There should be a file
called Use.htm installed on your system that will help a little.

Thanks, but that only allows moving forward.

It seems that I have no choice but to re-run gs whenever I need to
change resolution or move between pages.

Ghostview (gv) does almost exactly what you need. Take a look at how it works. It uses gs for rendering.
