## DESCRIPTION
       **ALTER** **TEXT** **SEARCH** **CONFIGURATION** changes the definition of a text search configuration. You
       can modify its mappings from token types to dictionaries, 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_.

       _new_name_
           The new name of the text search configuration.

       _new_owner_
           The new owner of the text search configuration.

       _new_schema_
           The new schema for 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.
