  12.    <code class="command">ALTER SUBSCRIPTION</code> can change most of the subscription

  13.    properties that can be specified

  14.    in <a class="xref" href="sql-createsubscription.html" title="CREATE SUBSCRIPTION"><span class="refentrytitle">CREATE SUBSCRIPTION</span></a>.

  15.   </p><p>

  16.    You must own the subscription to use <code class="command">ALTER SUBSCRIPTION</code>.

  17.    To alter the owner, you must also be a direct or indirect member of the

  18.    new owning role. The new owner has to be a superuser.

  19.    (Currently, all subscription owners must be superusers, so the owner checks

  20.    will be bypassed in practice.  But this might change in the future.)

  29.       <a class="xref" href="sql-createsubscription.html" title="CREATE SUBSCRIPTION"><span class="refentrytitle">CREATE SUBSCRIPTION</span></a> for more information.

  30.       By default this command will also act like <code class="literal">REFRESH

  31.       PUBLICATION</code>.

  32.      </p><p>

  33.       <em class="replaceable"><code>set_publication_option</code></em> specifies additional

  37.           When false, the command will not try to refresh table information.

  38.           <code class="literal">REFRESH PUBLICATION</code> should then be executed separately.

  45.       Fetch missing table information from publisher.  This will start

  46.       replication of tables that were added to the subscribed-to publications

  47.       since the last invocation of <code class="command">REFRESH PUBLICATION</code> or

  48.       since <code class="command">CREATE SUBSCRIPTION</code>.

  55.           being subscribed to should be copied once the replication starts.
