Update the reference pages for various ALTER commands that mentioned that you must be a member of role that will be the new owner to instead say that you must be able to SET ROLE to the new owner. Update ddl.sgml's generate statement on this topic along similar lines. Likewise, update CREATE SCHEMA and CREATE DATABASE, which have options to specify who will own the new objects, to say that you must be able to SET ROLE to the role that will own them. Finally, update the documentation for the GRANT statement itself with some general principles about how the SET option works and how it can be used. Patch by me, reviewed (but not fully endorsed) by Noah Misch. Discussion: http://postgr.es/m/CA+TgmoZk6VB3DQ83+DO5P_HP=M9PQAh1yj-KgeV30uKefVaWDg@mail.gmail.com

<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 be able to
|
|
<literal>SET ROLE</literal> to 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.)
