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 | CURRENT_USER | SESSION_USER }
       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.
