Here I attached update patch with further changes,
1. Explain plan changes for parallel grouping

2. Temporary fix for float aggregate types in _equalAggref because of
a change in aggtype to trans type, otherwise the parallel aggregation
plan failure in set_plan_references. whenever the aggtype is not matched,
it verifies with the trans type also.

3. Generates parallel path for all partial paths and add it to the path_list,
based on the cheapest_path, the plan is chosen.

To apply this patch, first apply the patch in [1]
