Fix schema in rangefuncs_cdb ICG test
The schema is named differently from the one being used in the
search_path so all the tables, views, functions, and etc. were
incorrectly being created in the public schema.
SELECT name, setting FROM pg_settings WHERE name LIKE 'enable%';
-- start_ignore
-create schema rangefuns_cdb;
+create schema rangefuncs_cdb;
set search_path to rangefuncs_cdb, public;
-- end_ignore
