I still advocate to folks to try to put contrib modules into thier own schemas 
whenever possible, so that you have the option of doing pg_dump -N 
contribmodule, makes things like this much easier to work around.  (And yes, 
I've volunteered to patch the contribs with this if we ever decide to make it 
the default setup)
