Put the citext stuff in a schema that *is* in everyone's search path.
It doesn't have to be "public", but it does have to be visible.

The only way to have an error be thrown would be if you remove the
implicit cast from citext to text ... which is going to be a far worse
notational pain in the rear than fixing your search_path.
