      <para>
       Altering the <literal>publish_via_partition_root</literal> parameter can
       lead to data loss or duplication at the subscriber because it changes
       the identity and schema of the published tables. Note this happens only
       when a partition root table is specified as the replication target.
      </para>
      <para>
       This problem can be avoided by refraining from modifying partition leaf
       tables after the <command>ALTER PUBLICATION ... SET</command> until the
       <link linkend="sql-altersubscription"><command>ALTER SUBSCRIPTION ... REFRESH PUBLICATION</command></link>
       is executed and by only refreshing using the <literal>copy_data = off</literal>
       option.
