    How about using a system column eg, ctid, for the CASE WHEN

    r1.ename, r1.job, r1.mgr, r1.hiredate, r1.sal, r1.comm, r1.deptno)
    END".  IMO I think that that would be much simpler than Ashutosh's

A foreign table can have a view, a regular table, another foreign table
or a materialised view a its target. A view does not support any of the
system columns, so none of them are available.

You are right.  Sorry for the noise.
