Hmm. This seems to be fixed in HEAD:
regression=# create table t (
regression(# );
CREATE TABLE
regression=# alter table t add childs t;
ALTER TABLE
regression=# alter table t add id serial not null primary key;
NOTICE: ALTER TABLE will create implicit sequence "t_id_seq" for serial column
"t.id"
NOTICE: ALTER TABLE / ADD PRIMARY KEY will create implicit index "t_pkey" for
table "t"
ERROR: cannot alter table "t" because column "t"."childs" uses its rowtype
Interestingly, 8.2 also says the same --- but 8.3, 8.4, and 9.0 crash.
Looks like we broke the error check somewhere along the way, and whoever
fixed it neglected to back-patch.
