Since some preparation work had already been done, the only source changes left were changing empty-element tags like <xref linkend="foo"> to <xref linkend="foo"/>, and changing the DOCTYPE. The source files are still named *.sgml, but they are actually XML files now. Renaming could be considered later. In the build system, the intermediate step to convert from SGML to XML is removed. Everything is build straight from the source files again. The OpenSP (or the old SP) package is no longer needed. The documentation toolchain instructions are updated and are much simpler now.

<para>
|
|
<command>ALTER SERVER</command> changes the definition of a foreign
|
|
server. The first form changes the server version string or the
|
|
generic options of the server (at least one clause is required).
|
|
The second form changes the owner of the server.
|

</para>
|

<para>
|
|
To alter the server you must be the owner of the server.
|
|
Additionally to alter the owner, you must own the server and also
|
|
be a direct or indirect member of the new owning role, and you must
|
|
have <literal>USAGE</literal> privilege on the server's foreign-data
|
|
wrapper. (Note that superusers satisfy all these criteria
|
|
automatically.)
