-# The t1b and t2d indexes are not very selective.  It used to be that
-# the autoindex mechanism would create automatic indexes on t1(b) or
-# t2(d), make assumptions that they were reasonably selective, and use
-# them instead of t1b or t2d.  But that would be cheating, because the
-# automatic index cannot be any more selective than the real index.

-# This test verifies that the cheat is no longer allowed.
