609959285b When computing STAT1 values using ANALYZE, if a ratio comes out to be between 
1.0 and 1.1, then round it down to 1 rather than the using the default rounding
rule of changing it to 2.  The reduces the estimation error for the
case where a column value is very nearly, but not quite unique.
