I think any deisgn needs to cater for attr dependencies. eg.

create table a (f1 int4, f2 int8);
create view view_a as select f2 from a;

Then

alter table a drop f1; -- Is OK. Should just happen
alter table a drop f2; -- Should warn about the view, and/or cascade etc.
alter table a alter f2 float; -- Should trigger a view recompilation.

...same thing needs to happen with constraints that reference attrs

I *think* tables are the only items that can have subobjects with dependant.
