DESCRIPTION

       ALTER TEXT SEARCH CONFIGURATION changes the definition of a text search configuration. You can modify its mappings from token types to dic-
       tionaries, 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 mapping.

       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 consulted 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  dictionaries  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 standard.
