Ok, I've now gotten rid of the PartialAggref node, and I'm actually
quite happy with how it turned out. I made
search_indexed_tlist_for_partial_aggref() to follow-on the series of
other search_indexed_tlist_for_* functions and have made it behave the
same way, by returning the newly created Var instead of doing that in
fix_combine_agg_expr_mutator(), as the last version did.

Thanks for the suggestion.

New patch attached.
