Really? I get

regression=# CREATE TYPE droppabletype1 AS (a integer, b text);
CREATE TYPE
regression=# CREATE TABLE testtable (droppablecol1 droppabletype1, undroppablecol1 int);
CREATE TABLE
regression=# CREATE TYPE droppabletype2 AS (a integer, b text);
CREATE TYPE
regression=# alter table testtable add column f3 droppabletype2;
ALTER TABLE
regression=# select pg_describe_object(classid,objid,objsubid) as obj, pg_describe_object(refclassid,refobjid,refobjsubid) as ref, deptype from pg_depend where refobjid = 'droppabletype1'::regtype;
obj | ref | deptype
--------------------------------------+---------------------+---------
composite type droppabletype1 | type droppabletype1 | i
type droppabletype1[] | type droppabletype1 | i
table testtable column droppablecol1 | type droppabletype1 | n
(3 rows)

regression=# select pg_describe_object(classid,objid,objsubid) as obj, pg_describe_object(refclassid,refobjid,refobjsubid) as ref, deptype from pg_depend where refobjid = 'droppabletype2'::regtype;
obj | ref | deptype
-------------------------------+---------------------+---------
composite type droppabletype2 | type droppabletype2 | i
type droppabletype2[] | type droppabletype2 | i
table testtable column f3 | type droppabletype2 | n
(3 rows)

The dependencies look just the same to me ...
