ALTER SERVER
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.
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 USAGE
privilege on the server's foreign-data
wrapper. (Note that superusers satisfy all these criteria
automatically.)
name

new_version
New server version.
OPTIONS ( [ ADD | SET | DROP ] option
['value
'] [, ... ] )
Change options for the
server. ADD
, SET
, and DROP

if no operation is explicitly specified. Option names must be
unique; names and values are also validated using the server's
foreign-data wrapper library.
new_owner
The user name of the new owner of the foreign server.
new_name
The new name for the foreign server.
