I found a bug in v10 patchset: when we generate the GROUP BY clauses for the partial aggregation that is pushed down to a non-aggregated relation, we may produce a clause with a tleSortGroupRef that duplicates one already present in the query's groupClause, which would cause problems.
Attached is the updated version of the patchset that fixes this bug and includes further code refactoring.
The v11-0002 git am failed on HEAD(6c2b5edecc).
