It looks like INSERT INTO ... RETURNING allows defining a target for the

returned values like SELECT ... INTO does.

 

That isn't how it works. RETURNING simply turns INSERT into a result set

producing SQL Command. And SQL doesn't have a concept of "target"

(variables) in the sense you are thinking. pg/pgsql does, allowing result

set data to be placed into variables.

 

Right. And in fact this *is* documented in the context of pl/pgsql:
