NAME
       ALTER TEXT SEARCH DICTIONARY - change the definition of a text search dictionary


SYNOPSIS
       ALTER TEXT SEARCH DICTIONARY name (
           option [ = value ] [, ... ]
       )
       ALTER TEXT SEARCH DICTIONARY name RENAME TO newname
       ALTER TEXT SEARCH DICTIONARY name OWNER TO newowner


DESCRIPTION
       ALTER  TEXT  SEARCH  DICTIONARY changes the definition of a text search dictionary.
       You can change the dictionary's template-specific options, or  change  the  dictio-
       nary's name or owner.

       You must be the owner of the dictionary to use ALTER TEXT SEARCH DICTIONARY.

PARAMETERS
       name   The  name  (optionally  schema-qualified) of an existing text search dictio-
              nary.

       option The name of a template-specific option to be set for this dictionary.

       value  The new value to use for a template-specific option.  If the equal sign  and
              value  are omitted, then any previous setting for the option is removed from
              the dictionary, allowing the default to be used.

       newname
              The new name of the text search dictionary.

       newowner
              The new owner of the text search dictionary.

       Template-specific options can appear in any order.


EXAMPLES
       The following example command changes the stopword list for a  Snowball-based  dic-
       tionary. Other parameters remain unchanged.

       ALTER TEXT SEARCH DICTIONARY my_dict ( StopWords = newrussian );


       The following example command changes the language option to dutch, and removes the
       stopword option entirely.

       ALTER TEXT SEARCH DICTIONARY my_dict ( language = dutch, StopWords );


       The following example command ''updates'' the dictionary's definition without actu-
       ally changing anything.

       ALTER TEXT SEARCH DICTIONARY my_dict ( dummy );

       (The reason this works is that the option removal code doesn't complain if there is
       no such option.) This trick is useful when changing  configuration  files  for  the
       dictionary: the ALTER will force existing database sessions to re-read the configu-
       ration files, which otherwise they would never do if they had read them earlier.

COMPATIBILITY
       There is no ALTER TEXT SEARCH DICTIONARY statement in the SQL standard.
