Why is that a problem? If you keep your object definitions in files
(e.g., in a directory structure that's under revision control) then
you can write a deployment script like the following (to be executed
via psql):

BEGIN;
DROP VIEW view_name;
ALTER TABLE table_name ALTER column_name TYPE type_name;
\i views/view_name.sql
COMMIT;
