Previous PR #4307 mark `partialize_agg` and `finalize_agg` as parallel safe but this change is leading to incorrect results in some cases. Those functions are supposed work in parallel but seems is not the case and it is not evident yet the root cause and how to properly use it in parallel queries so we decided to revert this change and provide correct results to users. Fixes #4922
