40357f0d5d Fix the query flattener so that it refuses a flattening that might leave both 
an inner-join and outer-join ON-clause constraint (or equivalent) on the same
term of the FROM clause.

093dd41e97 Do not allow a partial index scan on the left table of a RIGHT JOIN, because 
since the index is partial, some rows will be omitted from the scan, and
those rows will subsequently be picked up by the no-match logic in the
right-join post-processing loop.
