SERVER(7) PostgreSQL 9.2.7 Documentation CREATE SERVER(7) NAME
CREATE_SERVER - define a new foreign server SYNOPSIS
CREATE SERVER 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
server_name The name of the foreign server to be created. server_type Optional server type. server_version Optional server version. 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 (see dblink), the foreign server name can be used as an argument of the dblink_connect(3) function to indicate the connection parameters. See also there for more examples. 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 foo that uses the built-in foreign-data wrapper default: CREATE SERVER foo FOREIGN DATA WRAPPER "default"; Create a server myserver that uses the foreign-data wrapper pgsql: CREATE SERVER myserver FOREIGN DATA WRAPPER pgsql OPTIONS (host 'foo', dbname 'foodb', port '5432'); COMPATIBILITY

CREATE FOREIGN DATA WRAPPER - define a new foreign-data wrapper SYNOPSIS
CREATE FOREIGN DATA WRAPPER name [ VALIDATOR valfunction | NO VALIDATOR ] [ OPTIONS ( option 'value' [, ... ] ) ] DESCRIPTION
CREATE FOREIGN DATA WRAPPER creates a new foreign-data wrapper. The user who defines a foreign-data wrapper becomes its owner. The foreign-data wrapper name must be unique within the database. Only superusers can create foreign-data wrappers. PARAMETERS
name The name of the foreign-data wrapper to be created. VALIDATOR valfunction valfunction is the name of a previously registered function that will be called to check the generic options given to the foreign- data wrapper, as well as to foreign servers and user mappings using the foreign-data wrapper. If no validator function or NO VALIDA- TOR is specified, then options will not be checked at creation time. (Foreign-data wrappers will possibly ignore or reject invalid option specifications at run time, depending on the implementation.) The validator function must take two arguments: one of type text[], which will contain the array of options as stored in the system catalogs, and one of type oid, which will be the OID of the system catalog containing the options. The return type is ignored; the function should indicate invalid options using the ereport() function. OPTIONS ( option 'value' [, ... ] ) This clause specifies options for the new foreign-data wrapper. The allowed option names and values are specific to each foreign data wrapper and are validated using the foreign-data wrapper library. Option names must be unique. NOTES
At the moment, the foreign-data wrapper functionality is very rudimentary. The purpose of foreign-data wrappers, foreign servers, and user mappings is to store this information in a standard way so that it can be queried by interested applications. One such application is dblink; see in the documentation. The functionality to actually query external data through a foreign-data wrapper library does not exist yet. There is currently one foreign-data wrapper validator function provided: postgresql_fdw_validator, which accepts options corresponding to libpq connection parameters. EXAMPLES
Create a foreign-data wrapper dummy: CREATE FOREIGN DATA WRAPPER dummy; Create a foreign-data wrapper postgresql with validator function postgresql_fdw_validator: CREATE FOREIGN DATA WRAPPER postgresql VALIDATOR postgresql_fdw_validator; Create a foreign-data wrapper mywrapper with some options: CREATE FOREIGN DATA WRAPPER mywrapper OPTIONS (debug 'true'); COMPATIBILITY
CREATE FOREIGN DATA WRAPPER conforms to ISO/IEC 9075-9 (SQL/MED), with the exception that the VALIDATOR clause is an extension and the clauses LIBRARY and LANGUAGE are not yet implemented in PostgreSQL. Note, however, that the SQL/MED functionality as a whole is not yet conforming. SEE ALSO
