DELETE ... RETURNING is useful for this kind of thing, sometimes. And
you could use it inside a function to go and do something with each
row returned, though that might not be very graceful for large numbers
of rows. The proposed syntax wouldn't actually work because it
doesn't specify where to put the data.
