Usually it's a mistake to directly select HLL or bitmap column without applying function on it. In order to work around the "select *" queries issued automatically by BI tools, we could return NULL for HLL and bitmap columns by default. For users who want to get the raw binary of HLL and bitmap, we could add a configuration like `return_raw_value_for_complex_type` to support such scenario.
