schemas/util.sql: diff(text, text): removed unnecessary casts to the base type in the join condition and the WHERE filter. these had been presumed necessary due to errors, but the errors turned out to be caused by the operator not being in the search_path. note that the casts in the columns list are still needed, as described in the associated comment.
