No ...
CREATE VIEW level1 AS SELECT * FROM base_table;
CREATE VIEW level2 AS SELECT * FROM level1;
You can't drop level1 without dropping level2; the composite type
associated with level1 doesn't enter into that. I'd actually
find it rather surprising if there are many real-world cases where
other objects have a dependency on a view's composite type but not
on the view itself.
