ALTER SERVER
ALTER SERVER
Changes the definition of a foreign server.
Synopsis
ALTER SERVER server_name [ VERSION 'new_version' ] [ OPTIONS ( [ ADD | SET | DROP ] option ['value'] [, ... ] ) ] ALTER SERVER server_name OWNER TO new_owner ALTER SERVER server_name RENAME TO new_name
Description
ALTER SERVER changes the definition of a foreign server. The first form of the command changes the version string or the generic options of the server. Greenplum Database requires at least one clause. The second and third forms of the command change the owner or the name of the server.
- Own the server.
- Be a direct or indirect member of the new owning role.
- Have USAGE privilege on the server's foreign-data wrapper.
Superusers automatically satisfy all of these criteria.
Parameters
- server_name
-
The name of an existing server.
- new_version
-
The new server version.
- OPTIONS ( [ ADD | SET | DROP ] option ['value'] [, ... ] )
-
Change the server's options. ADD, SET, and DROP specify the action to perform. If no operation is explicitly specified, the default operation is ADD. Option names must be unique. Greenplum Database validates names and values using the server's foreign-data wrapper library.
- OWNER TO new_owner
-
Specifies the new owner of the foreign server.
- RENAME TO new_name
-
Specifies the new name of the foreign server.
Examples
Change the definition of a server named foo by adding connection options:
ALTER SERVER foo OPTIONS (host 'foo', dbname 'foodb');
Change the option named host for a server named foo, and set the server version:
ALTER SERVER foo VERSION '9.1' OPTIONS (SET host 'baz');
Compatibility
ALTER SERVER conforms to ISO/IEC 9075-9 (SQL/MED). The OWNER TO and RENAME forms are Greenplum Database extensions.
