Maybe this is obvious, but just in case: gist_page_items is *very*
trusting here. It's necessary to use gist_page_items_bytea() if you're
not 100% sure about the index definition for the index page you
provide. The fact that you can display the contents of each tuple
using the underlying type's own output function is very handy. But
potentially hazardous.
