CREATE FOREIGN 
TABLE(7) 				  PostgreSQL 9.2.7 Documentation				   CREATE FOREIGN TABLE(7)

NAME

       CREATE_FOREIGN_TABLE - define a new foreign table

SYNOPSIS

       CREATE FOREIGN TABLE [ IF NOT EXISTS ] table_name ( [
	 { column_name data_type [ OPTIONS ( option 'value' [, ... ] ) ] [ NULL | NOT NULL ] }
	   [, ... ]
       ] )
	 SERVER server_name
       [ OPTIONS ( option 'value' [, ... ] ) ]

DESCRIPTION

       CREATE FOREIGN TABLE will create a new foreign table in the current database. The table will be owned by the user issuing the command.

       If a schema name is given (for example, CREATE FOREIGN TABLE myschema.mytable ...) then the table is created in the specified schema.
       Otherwise it is created in the current schema. The name of the foreign table must be distinct from the name of any other foreign table,
       table, sequence, index, or view in the same schema.

       CREATE FOREIGN TABLE also automatically creates a data type that represents the composite type corresponding to one row of the foreign
       table. Therefore, foreign tables cannot have the same name as any existing data type in the same schema.

       To be able to create a table, you must have USAGE privilege on all column types.

PARAMETERS

       IF NOT EXISTS
	   Do not throw an error if a relation with the same name already exists. A notice is issued in this case. Note that there is no guarantee
	   that the existing relation is anything like the one that would have been created.

       table_name
	   The name (optionally schema-qualified) of the table to be created.

       column_name
	   The name of a column to be created in the new table.

       data_type
	   The data type of the column. This can include array specifiers. For more information on the data types supported by PostgreSQL, refer
	   to Chapter 8, Data Types, in the documentation.

       NOT NULL
	   The column is not allowed to contain null values.

       NULL
	   The column is allowed to contain null values. This is the default.

	   This clause is only provided for compatibility with non-standard SQL databases. Its use is discouraged in new applications.

       server_name
	   The name of an existing server for the foreign table.

       OPTIONS ( option 'value' [, ...] )
	   Options to be associated with the new foreign table or one of its columns. The allowed option names and values are specific to each
	   foreign data wrapper and are validated using the foreign-data wrapper's validator function. Duplicate option names are not allowed
	   (although it's OK for a table option and a column option to have the same name).

EXAMPLES

       Create foreign table films with film_server:

	   CREATE FOREIGN TABLE films (
	       code	   char(5) NOT NULL,
	       title	   varchar(40) NOT NULL,
	       did	   integer NOT NULL,
	       date_prod   date,
	       kind	   varchar(10),
	       len	   interval hour to minute
	   )
	   SERVER film_server;

COMPATIBILITY

       The CREATE FOREIGN TABLE command largely conforms to the SQL standard; however, much as with CREATE TABLE, NULL constraints and zero-column
       foreign tables are permitted.

ALTER FOREIGN DATA 
WRAPPER(7)				  PostgreSQL 9.2.7 Documentation			     ALTER FOREIGN DATA WRAPPER(7)

NAME

       ALTER_FOREIGN_DATA_WRAPPER - change the definition of a foreign-data wrapper

SYNOPSIS

       ALTER FOREIGN DATA WRAPPER name
	   [ HANDLER handler_function | NO HANDLER ]
	   [ VALIDATOR validator_function | NO VALIDATOR ]
	   [ OPTIONS ( [ ADD | SET | DROP ] option ['value'] [, ... ]) ]
       ALTER FOREIGN DATA WRAPPER name OWNER TO new_owner
       ALTER FOREIGN DATA WRAPPER name RENAME TO new_name

DESCRIPTION

       ALTER FOREIGN DATA WRAPPER changes the definition of a foreign-data wrapper. The first form of the command changes the support functions or
       the generic options of the foreign-data wrapper (at least one clause is required). The second form changes the owner of the foreign-data
       wrapper.

       Only superusers can alter foreign-data wrappers. Additionally, only superusers can own foreign-data wrappers.

PARAMETERS

       name
	   The name of an existing foreign-data wrapper.

       HANDLER handler_function
	   Specifies a new handler function for the foreign-data wrapper.

       NO HANDLER
	   This is used to specify that the foreign-data wrapper should no longer have a handler function.

	   Note that foreign tables that use a foreign-data wrapper with no handler cannot be accessed.

       VALIDATOR validator_function
	   Specifies a new validator function for the foreign-data wrapper.

	   Note that it is possible that after changing the validator the options to the foreign-data wrapper, servers, and user mappings have
	   become invalid. It is up to the user to make sure that these options are correct before using the foreign-data wrapper.

       NO VALIDATOR
	   This is used to specify that the foreign-data wrapper should no longer have a validator function.

       OPTIONS ( [ ADD | SET | DROP ] option ['value'] [, ... ] )
	   Change options for the foreign-data wrapper.  ADD, SET, and DROP specify the action to be performed.  ADD is assumed if no operation is
	   explicitly specified. Option names must be unique; names and values are also validated using the foreign data wrapper's validator
	   function, if any.

       new_owner
	   The user name of the new owner of the foreign-data wrapper.

       new_name
	   The new name for the foreign-data wrapper.

EXAMPLES

       Change a foreign-data wrapper dbi, add option foo, drop bar:

	   ALTER FOREIGN DATA WRAPPER dbi OPTIONS (ADD foo '1', DROP 'bar');

       Change the foreign-data wrapper dbi validator to bob.myvalidator:

	   ALTER FOREIGN DATA WRAPPER dbi VALIDATOR bob.myvalidator;

COMPATIBILITY

       ALTER FOREIGN DATA WRAPPER conforms to ISO/IEC 9075-9 (SQL/MED), except that the HANDLER, VALIDATOR, OWNER TO, and RENAME clauses are
       extensions.
