ALTER TEXT SEARCH DICTIONARY
changes the definition of a text search dictionary. You can change the dictionarys template-specific options, or change the dictionarys name or owner.
You must be the owner of the dictionary to use
ALTER TEXT SEARCH DICTIONARY.
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
the dictionarys definition without actually changing anything.
ALTER TEXT SEARCH DICTIONARY my_dict ( dummy );
(The reason this works is that the option removal code doesnt complain if there is no such option.) This trick is useful when changing configuration files for the dictionary: the
will force existing database sessions to re-read the configuration files, which otherwise they would never do if they had read them earlier.
