Postgres will prepend pg_temp to the effective search_path if it is not present in the search_path. While pg_temp will never be used to look up functions or operators unless explicitly requested pg_temp will be used to look up relations. Putting pg_temp in search_path makes sure objects in pg_temp will be considered last and pg_temp cannot be used to mask existing objects.
