Of course.  The former command implies that you are inserting a
composite value into a single composite-type column of expected_stuff,
which you are not.

The right way to express this IMHO is
    INSERT INTO archive.expected_stuff VALUES(o.*);
which should expand into the longhand notation "o.source,o.warehouse..."
in the same way that "SELECT o.* FROM ..." would do.  This does actually
work in 8.2 (and maybe 8.1, I forget).  In older releases you gotta
write it out longhand :-(
