<code class="command">ALTER SERVER</code> 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).

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 <code class="literal">USAGE</code> privilege on the server's foreign-data
wrapper. (Note that superusers satisfy all these criteria
automatically.)
