CLASS="QUOTE"
>"parameterized path"</SPAN
> mechanism allows inner
        index scans to use values from relations that are more than one join
        level up from the scan.  This can greatly improve performance in
        situations where semantic restrictions (such as outer joins) limit
        the allowed join orderings.
