The current example shows the usage of looping in plpgsql, so as such
there is no correctness issue, but OTOH there is no harm in updating
the example as proposed by Ian Barwick.  Does anyone else see any
problem with this idea?  If we agree to proceed with this update, it
might be better to backpatch it for the sake of consistency though I
am not sure about that.
