bug with alter table add column

Hi,

Under Postgresql 7.0.2 (linux86), I've just noticed a strange behavior (I
suppose it's a bug) with alter table, but don't know if it's a known one
or not:

the following works great:

db=> CREATE TABLE foo (id SERIAL);
NOTICE:  CREATE TABLE will create implicit sequence 'foo_id_seq' for
SERIAL column 'foo.id'
NOTICE:  CREATE TABLE/UNIQUE will create implicit index 'foo_id_key' for
table 'foo'
CREATE

db=> \ds
       List of relations
    Name    |   Type   | Owner
------------+----------+--------
 foo_id_seq | sequence | jerome
(1 row)


but the following doesn't create the sequence bar_id_seq:

db=> CREATE TABLE bar (somefield TEXT);
CREATE
db=> ALTER TABLE bar ADD COLUMN id SERIAL;
ALTER
db=> \ds
       List of relations
    Name    |   Type   | Owner
------------+----------+--------
 foo_id_seq | sequence | jerome
(1 row)


The ALTER command should have created a sequence named bar_id_seq, as well
as an index but has done none.

I suppose it's a bug.

also it would be fine if ALTER could rename other things than just tables;
