Foreign Keys referencing a View

From

Hi,
I noticed a behaviour in PostgreSql 7 (beta 3, Alpha, Digital Unix 4.0f,
cc) that probably needs to be addressed.

If I create a table referencing a view

create table mytable (id serial, name text);
create view myview as select * from mytable where name like 'A%';
create table othertable (id serial, refer integer references myview
(id));

the engine doesn't complain, but

insert into mytable (name) values ('Alpha');
insert into othertable (refer) values (1);
ERROR:  system column oid not available - myview is a view

which looks sensible. But probably the errors should have been raised at 
'create table othertable'.

What do you think?
