Log Message:
-----------
Original coding of 'returning' regression test inadvertently chose a
nonunique join value, leading to plan-choice-dependent results ... and
it seems some platforms will choose a different plan. Tweak the test
so that it has well-defined results. Per report from Olivier Prenant.
