Change the PathKey struct to use CompareType to record the sort direction instead of hardcoding btree strategy numbers. The CompareType is then converted to the index-type-specific strategy when the plan is created. This reduces the number of places btree strategy numbers are hardcoded, and it's a self-contained subset of a larger effort to allow non-btree indexes to behave like btrees.
