CREATE TABLE person (id SERIAL PRIMARY KEY, name TEXT NOT NULL);

BEGIN;
INSERT INTO person (name) VALUES ('Tom');
SAVEPOINT foo;
INSERT INTO person (name) VALUES ('Dick');
ROLLBACK TO foo;
INSERT INTO person (name) VALUES ('Harry');
COMMIT;

SELECT * FROM person;id | name  
----+------- 1 | Tom 3 | Harry
(2 rows)
