Currently the loose scan code in opt_range.cc considers all indexes as possible for the access method. Due to inexact statistics it may happen that a loose scan is selected over a unique index.
This is clearly wrong since a "loose scan" over a unique index will read the same keys as a direct index scan, but the loose scan has more overhead.
