> We currently only use a skip scan for a row value constructor equality or in list expression
is fully qualified. We can fairly easily use it when only some of the leading pk columns are
used.
> For example:
> {code}
> WHERE (a,b) IN ((1,2),(3,4))
> {code}
> If the PK is (a,b,c), we can still use a skip scan. We need to pass through the slotSpan
array in this case too, to the SkipScanFilter.
