Not necessarily. Consider this:

  CREATE TABLE t1 (
    id serial NOT NULL,
    val int NOT NULL,
    usr text NOT NULL,
    PRIMARY KEY (id)
  );

  COPY t1 (val, usr) FROM stdin;
  1    u1
  2    u1
  3    u2
  4    u3
  \.

  CREATE VIEW t1v (id, val) AS
  SELECT id, val
  FROM t1
  WHERE usr = current_user;

Now user "u1" can only see rows 1 and 2.
