>
> There are three types of outer-joins:
> - left outer,
> - right outer, and
> - full outer
> joins.
> An outer-join does not "filter" tuples of the outer-side that do not find a
> matching tuple on the other side. Instead, it is joined with a NULL value.
> Supporting outer-joins requires some modifications in the join execution
> strategies.
