Apply a simple solution to the problem of making INSERT/UPDATE/DELETE

rewrite any RETURNING clause found in a rule to produce what the rule's

the RETURNING clause if no RETURNING in the triggering query. This
leaves the responsibility for knowing how to produce the view's output
columns on the rule author, without requiring any fundamental changes
in rule semantics such as adding new rule event types would do. The
initial implementation constrains things to ensure that there is
exactly one, unconditionally invoked RETURNING clause among the rules
