2aa1086cab Preserve the COLLATE operator on an index on an expression when resolving 
the use of that expression into a reference to the index.  See
[forum:/info/7efabf4b03328e57|forum thread 7efabf4b03328e57] for details.

a25bbaf74a Further improvements to codeEqualityTerm() for cases when an IN operator with 
a right-hand side subquery is used as a constraint that needs to be processed
by the RIGHT JOIN non-matched logic.

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.
