If create a table and alter column add sequence. The relation on table and sequence is not present in pg_depend.
When drop table the sequence is not dropped.

What are you doing, exactly?  ADD COLUMN foo SERIAL doesn't work yet.

regression=# alter table vv add column f2 serial;
NOTICE:  ALTER TABLE will create implicit sequence 'vv_f2_seq' for SERIAL column 'vv.f2'
ERROR:  Adding columns with defaults is not implemented.
        Add the column, then use ALTER TABLE SET DEFAULT.

SET DEFAULT nextval('foo') does not create an auto-drop dependency,
and should not IMHO.
