ALTER TEXT SEARCH DICTIOPostgreSQL 9.6.3 DocumeALTERoTEXT SEARCH DICTIONARY(7)

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 new_name
       ALTER TEXT SEARCH DICTIONARY name OWNER TO { new_owner |	CURRENT_USER | SESSION_USER }
       ALTER TEXT SEARCH DICTIONARY name SET SCHEMA new_schema

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 dictionary'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
	   dictionary.

       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.

       new_name
	   The new name	of the text search dictionary.

       new_owner
	   The new owner of the	text search dictionary.

       new_schema
	   The new schema for 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 dictionary. 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 actually	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	configuration 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.
