Probably other places too.  I don't see any provision here for ensuring
that the variables used in the RETURNING list are actually computed by
the plan.  This would be masked in the INSERT and non-join UPDATE cases
by the fact that the plan has to compute all columns of the target table
anyway ... but in a DELETE it'd be an issue.

I think set-returning functions in the RETURNING list might give you
some fits too ...
