> It seems that the tests for rewrite rules depends on the famous SCOTT table
> from Oracle, yet it also seems unclear if there exists foreign key
> constraints between the EMP and DEPT tables. If there are such constraints,
> are they considered in any optimization rules (CoreRules)? And if so, are
> these constraints stored in RelOptTable?
