Use the following :

INSERT ... RETURNING expressions INTO [STRICT] target;
UPDATE ... RETURNING expressions INTO [STRICT] target;
DELETE ... RETURNING expressions INTO [STRICT] target;

http://www.postgresql.org/docs/9.1/static/plpgsql-statements.html

Else if you have multiple rows do something like:
FOR my_update IN UPDATE ... RETURNING * LOOP
