Attached patch fixes the issue for me.  I have locally verified that
the gather merge gets executed in rescan path.  I haven't added a test
case for the same as having gather or gather merge on the inner side
of join can be time-consuming.  However, if you or others feel that it
is important to have a test to cover this code path, then I can try to
produce one.
