DESCRIPTION
       ALTER TEXT SEARCH CONFIGURATION changes the definition of a text search
       configuration.  You can modify its mappings from token types to dictio‐
       naries, or change the configuration's name or owner.

       You must be the owner of the configuration to  use  ALTER  TEXT	SEARCH
       CONFIGURATION.

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

       token_type
	      The name of a token type that is emitted by the  configuration's
	      parser.

       dictionary_name
	      The  name	 of  a	text search dictionary to be consulted for the
	      specified token type(s). If multiple  dictionaries  are  listed,
	      they are consulted in the specified order.

       old_dictionary
	      The  name of a text search dictionary to be replaced in the map‐
	      ping.

       new_dictionary
	      The name of a text  search  dictionary  to  be  substituted  for
	      old_dictionary.

       newname
	      The new name of the text search configuration.

       newowner
	      The new owner of the text search configuration.

       The  ADD	 MAPPING  FOR  form installs a list of dictionaries to be con‐
       sulted for the specified token type(s); it is  an  error	 if  there  is
       already	a  mapping  for any of the token types.	 The ALTER MAPPING FOR
       form does the same, but first removing any existing mapping  for	 those
       token types.  The ALTER MAPPING REPLACE forms substitute new_dictionary
       for old_dictionary anywhere the latter appears.	This is done for  only
       the  specified token types when FOR appears, or for all mappings of the
       configuration when it doesn't.  The DROP MAPPING form removes all  dic‐
       tionaries  for  the  specified  token  type(s), causing tokens of those
       types to be ignored by the text search configuration. It is an error if
       there is no mapping for the token types, unless IF EXISTS appears.

EXAMPLES
       The  following example replaces the english dictionary with the swedish
       dictionary anywhere that english is used within my_config.

       ALTER TEXT SEARCH CONFIGURATION my_config
	 ALTER MAPPING REPLACE english WITH swedish;

COMPATIBILITY
       There is no ALTER TEXT SEARCH CONFIGURATION statement in the SQL	 stan‐
       dard.
