[TRAFODION-2130] Incorrect subquery unnesting
A missing ">" character caused us to do an unnesting transformation
without having uniqueness constraint on the main query.
Note that this is a rare case, since most tables have unique columns
and since the code tries to get those unique columns if they are not
already included.
