constraints on outer joins, and (3) ON/USING clause constraints on inner
joins. Formerly, there was no distinctionb between 1 and 3, but RIGHT JOIN
needs to know the difference. Make RIGHT JOIN aware of this difference and
add test cases.

automatic indexes must be WHERE_IDX_ONLY, but the RIGHT JOIN post-processing
does not know how to work with an index-only scan.

that are to the left of a RIGHT JOIN, to avoid other complications.

make sure all its columns are flushed to NULL when it finishes so that
they appear to be NULL during the RIGHT JOIN post-processing.
