ADS,
Just an elephant-logo mug probably won't go very far here; we were
practically forcing the EDB mugs on people (for free) once we got to the
last box.
Idea for a new mug design: do an instructional one of psql shortcuts,
per the vi coffee mug:

The other option in the US would be an *inexpensive* travel mug made
from recycled plastic, if we could locate such a thing; then we'd be
"green conferencing".
However, as before I think that merchandising isn't what it used to be
in the US, and here we should focus more on straight-up donations instead.
