Fix for 344d62fb9a: That commit introduced unlogged sequences and
made it so that identity/serial sequences automatically get the
persistence level of their owning table. But this works only for
CREATE TABLE and not for ALTER TABLE / ADD COLUMN. The latter would
always create the sequence as logged (default), independent of the
persistence setting of the table. This is fixed here.
Note: It is allowed to change the persistence of identity sequences
directly using ALTER SEQUENCE. So mistakes in existing databases can
be fixed manually.
