There's another potential issue I'm wondering about, related to reordering. If one of the earlier clauses is `RIGHT OUTER` or `FULL OUTER` (a "righty" join) then they generate nulls in columns associated with the base table, for any right-hand-side rows that don't match the join clause. In this case, it wouldn't be correct to reorder a later `INNER` join leftwards through the `RIGHT OUTER` or `FULL OUTER` clause. Please add a test case about this too. -- This is an automated message from the Apache Git Service.
