I have a query that runs extremely slow. When I ran the explain plan I noticed that there is a buffer sort whose cost accounts for almost all of the cost of the entire query.

The buffer sort is done on a full access of indexed and analyzed table with only 32 rows. Why is this happening and how could I reduce the cost of that step?
