ALTER TEX...ICTIONARY(7) PostgreSQL 18.6 Documentation ALTER TEX...ICTIONARY(7) NAME ALTER_TEXT_SEARCH_DICTIONARY - change the definition of a text search dic- tionary 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_ROLE | 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 dic- tionary. 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 DICTIO- NARY. PARAMETERS name The name (optionally schema-qualified) of an existing text search dic- tionary. 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 re- moved 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 Snow- ball-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 re- moves 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.
