Right now it just rejects the ALTER attempt:

regression=# create table t1 (f1 int);
CREATE TABLE
regression=# create view v1 as select * from t1;
CREATE VIEW
regression=# alter table t1 alter f1 type bigint;
ERROR:  cannot alter type of a column used by a view or rule
DETAIL:  rule _RETURN on view v1 depends on column "f1"
regression=#

Improving this per the previous discussion probably ought to be
mentioned in the TODO list.
