Syntax:
CREATE SERVER server_name
    FOREIGN DATA WRAPPER wrapper_name
    OPTIONS (option [, option] ...)

option:
  { HOST character-literal
  | DATABASE character-literal
  | USER character-literal
  | PASSWORD character-literal
  | SOCKET character-literal
  | OWNER character-literal
  | PORT numeric-literal }

This statement creates the definition of a server for use with the
FEDERATED storage engine. The CREATE SERVER statement creates a new row
within the servers table within the mysql database. This statement
requires the SUPER privilege.

The server_name should be a unique reference to the server. Server
definitions are global within the scope of the server, it is not
possible to qualify the server definition to a specific database.
server_name has a maximum length of 64 characters (names longer than 64
characters are silently truncated), and is case insensitive. You may
specify the name as a quoted string.

The wrapper_name should be mysql, and may be quoted with single quotes.
Other values for wrapper_name are not currently supported.

For each option you must specify either a character literal or numeric
literal. Character literals are UTF-8, support a maximum length of 64
characters and default to a blank (empty) string. String literals are
silently truncated to 64 characters. Numeric literals must be a number
between 0 and 9999, default value is 0.

*Note*: Note that the OWNER option is currently not applied, and has no
effect on the ownership or operation of the server connection that is
created.

The CREATE SERVER statement creates an entry in the mysql.server table
that can later be used with the CREATE TABLE statement when creating a
FEDERATED table. The options that you specify will be used to populate
the columns in the mysql.server table. The table columns are
Server_name, Host, Db, Username, Password, Port and Socket.
