CREATE SERVER(7) PostgreSQL 12.3 Documentation CREATE SERVER(7)
NAME
CREATE_SERVER - define a new foreign server
SYNOPSIS
CREATE SERVER [ IF NOT EXISTS ] server_name [ TYPE 'server_type' ] [ VERSION 'server_version' ]
FOREIGN DATA WRAPPER fdw_name
[ OPTIONS ( option 'value' [, ... ] ) ]
DESCRIPTION
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.
PARAMETERS
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
server's foreign-data wrapper.
NOTES
When using the dblink module, a foreign server's 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.
EXAMPLES
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.
COMPATIBILITY
CREATE SERVER conforms to ISO/IEC 9075-9 (SQL/MED).
