Yes yes. Maybe I was imprecise. Right join and left join are the same,
only the ordering is different. Lets call the table that will always be
included in a join a "complete" table. 

Then, joins should not impose join order on "complete" table. Of course,
joins against 'incomplete' table must be done only after outer join is
done.

Anyone who can actually fix it? :)
