ALTER 
SERVER(7) 					  PostgreSQL 9.2.7 Documentation					   ALTER SERVER(7)

NAME

       ALTER_SERVER - change the definition of a foreign server

SYNOPSIS

       ALTER SERVER name [ VERSION 'new_version' ]
	   [ OPTIONS ( [ ADD | SET | DROP ] option ['value'] [, ... ] ) ]
       ALTER SERVER name OWNER TO new_owner
       ALTER SERVER name RENAME TO new_name

DESCRIPTION

       ALTER SERVER changes the definition of a foreign server. The first form changes the server version string or the generic options of the
       server (at least one clause is required). The second form changes the owner of the server.

       To alter the server you must be the owner of the server. Additionally to alter the owner, you must own the server and also be a direct or
       indirect member of the new owning role, and you must have USAGE privilege on the server's foreign-data wrapper. (Note that superusers
       satisfy all these criteria automatically.)

PARAMETERS

       name
	   The name of an existing server.

       new_version
	   New server version.

       OPTIONS ( [ ADD | SET | DROP ] option ['value'] [, ... ] )
	   Change options for the server.  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 server's foreign-data wrapper library.

       new_owner
	   The user name of the new owner of the foreign server.

       new_name
	   The new name for the foreign server.

EXAMPLES

       Alter server foo, add connection options:

	   ALTER SERVER foo OPTIONS (host 'foo', dbname 'foodb');

       Alter server foo, change version, change host option:

	   ALTER SERVER foo VERSION '8.4' OPTIONS (SET host 'baz');

COMPATIBILITY

       ALTER SERVER conforms to ISO/IEC 9075-9 (SQL/MED). The OWNER TO and RENAME forms are PostgreSQL extensions.

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.
