CREATE_SERVER - define a new foreign server
CREATE SERVER [ IF NOT EXISTS ] server_name [ TYPE server_type ] [ VERSION server_version ]
FOREIGN DATA WRAPPER fdw_name
[ OPTIONS ( option value [, ... ] ) ]CREATE SERVER defines a new foreign server. The user who defines the server becomes its owner.
A foreign server typically encapsulates connection information that a foreign-data wrapper uses to access an external data resource. Additional user-specific connection information may be specified by means of user mappings.
The server name must be unique within the database.
Creating a server requires USAGE privilege on the foreign-data wrapper being used.
IF NOT EXISTS
Do not throw an error if a server with the same name already exists. A notice is issued in this case. Note that there is no guarantee that the existing server is anything like the one that would have been created.
server_name
The name of the foreign server to be created.
server_type
Optional server type, potentially useful to foreign-data wrappers.
server_version
Optional server version, potentially useful to foreign-data wrappers.
fdw_name
The name of the foreign-data wrapper that manages the server.
OPTIONS ( option value [, ... ] )
This clause specifies the options for the server. The options typically define the connection details of the server, but the actual names and values are dependent on the servers foreign-data wrapper.
When using the dblink module, a foreign servers name can be used as an argument of the dblink_connect(3) function to indicate the connection parameters. It is necessary to have the USAGE privilege on the foreign server to be able to use it in this way.
Create a server myserver that uses the foreign-data wrapper postgres_fdw:
CREATE SERVER myserver FOREIGN DATA WRAPPER postgres_fdw OPTIONS (host foo, dbname foodb, port 5432);
See postgres_fdw for more details.
CREATE SERVER conforms to ISO/IEC 9075-9 (SQL/MED).
