Major Description
For example we have multiple PK columns (pk0, pk1, pk2) for table A, if we do a IN subquery or join query with all PK columns, like:
select * from A where (pk0, pk1, pk2) IN (select pk0, pk1, pk2 from B);
The child/parent join optimization is supposed to use the entire PK "(pk0, pk1, pk2)" for constructing the dynamic skip-scan filter.
However it would only use (pk0, pk1) instead, missing the last PK part.
