Alexander Korotkov 3d3a81fc24 Fix tuple_fraction calculation in generate_orderedappend_paths() 
6b94e7a6da adjusted generate_orderedappend_paths() to consider fractional
paths.  However, it didn't manage to interpret the tuple_fraction value
correctly.  According to the header comment of grouping_planner(), the
tuple_fraction >= 1 specifies the absolute number of expected tuples.  That
number must be divided by the expected total number of tuples to get the
actual fraction.

Even though this is a bug fix, we don't backpatch it.  The risks of the side
effects of plan changes on stable branches are too high.
