Note that in the case of a regular non-skip scan, this cursor backwards works because the Unique node on top does not support backwards scanning at all. Therefore, when creating the cursor, the actual plan actually contains a Materialize node on top of the Unique+Index Scan nodes. The 'fetch backwards' never reaches the the index scan therefore, as it just fetches stuff from the materialize node. -Floris
