Huh?  I see

   <varlistentry id="sql-altertable-desc-generated-identity">
    <term><literal>ADD GENERATED { ALWAYS | BY DEFAULT } AS IDENTITY</literal></term>
    <term><literal>SET GENERATED { ALWAYS | BY DEFAULT }</literal></term>
    <term><literal>DROP IDENTITY [ IF EXISTS ]</literal></term>
    <listitem>
     <para>
      These forms change whether a column is an identity column or change the
      generation attribute of an existing identity column.
      See <link linkend="sql-createtable"><command>CREATE TABLE</command></link> for details.

Where do you see a pointer to CREATE SEQUENCE on that page?
