Log Message:
-----------
Add a fudge factor to genericcostestimate() to prevent the planner from
thinking that indexes of different sizes are equally attractive. Per
gripe from Jim Nasby. (I remain unconvinced that there's such a problem
in existing releases, but CVS HEAD definitely has got a problem because
of its new count-only-leaf-pages approach to indexscan costing.)
