yes, this is possible:

postgres=# create table t(i int);
CREATE TABLE
postgres=# create view v(i) as select i from t;
CREATE VIEW
postgres=# insert into v(i) values (0);
INSERT 0 1
postgres=# select * from v;
 i
---
 0
(1 row)

postgres=# update v set i=3;
UPDATE 1
postgres=# select * from v;
 i
---
 3
(1 row)

But I don't know since which PostgreSQL version views can up updated.
