Hmm, interesting thought.  The knock against doing RETURNING as an
ordinary subquery is exactly that you can't disentangle it very well
from the upper query (and thus, it's hard to figure out when to fire
triggers, to take just one problem).  But we've defined CTEs much more
restrictively, so maybe the problems can be solved in that context.
