-# This file implements tests of the "skip-scan" query strategy. In 
-# particular, this file verifies that use of all columns of an index
-# is always preferred over the use of a skip-scan on some columns of
-# the same index.  Because of difficulties in scoring a skip-scan,
-# the skip-scan can sometimes come out with a lower raw score when
-# using STAT4.  But the query planner should detect this and use the
-# full index rather than the skip-scan.
