I don't think so.
regression=# create table t1 (f1 int, f2 int);
CREATE TABLE
regression=# create user joe;
CREATE ROLE
regression=# grant update on table t1 to joe;
GRANT
regression=# \c - joe
You are now connected to database "regression" as user "joe".
regression=> update t1 set f1 = 1;
UPDATE 0
regression=> update t1 set f1 = 1 where f2 = 3;
ERROR: permission denied for relation t1
regression=> select version();
version

It's acted that way for a very very long time.
