SEQUENCES and COPY FROM

In the process of upgrading from 6.1 to 6.3.2+patches at long last.
Just bumped into an interesting
problem with sequences. With 6.1, you could use sequences with COPY
FROM. This no longer
seems to be true with 6.3.2+patches. INSERT and UPDATE still work fine
but when using COPY FROM
all sequence fields are either 0 or NULL.

Can live without but curious if it's a bug or feature? Maybe fixed in
6.4? Wasn't COPY FROM changed
at the time pg_shadow was added?

Here's the affected schema:

CREATE SEQUENCE history_seq;

CREATE TABLE history (
gid INTEGER,
state TEXT,
dtin DATETIME,
dtout DATETIME,
seqno INTEGER DEFAULT nextval('history_seq') NOT NULL
);
