19 ALTER TEXT SEARCH DICTIONARY changes the definition of a text search
20 dictionary. You can change the dictionary's template-specific options,
21 or change the dictionary's name or owner.
22
23 You must be the owner of the dictionary to use ALTER TEXT SEARCH DIC‐
24 TIONARY.
25
27 name The name (optionally schema-qualified) of an existing text
28 search dictionary.
29
30 option The name of a template-specific option to be set for this dic‐
31 tionary.
32
33 value The new value to use for a template-specific option. If the
34 equal sign and value are omitted, then any previous setting for
35 the option is removed from the dictionary, allowing the default
36 to be used.
37
38 newname
39 The new name of the text search dictionary.
40
41 newowner
42 The new owner of the text search dictionary.
43
44 Template-specific options can appear in any order.

47 The following example command changes the stopword list for a Snowball-
48 based dictionary. Other parameters remain unchanged.
49
50 ALTER TEXT SEARCH DICTIONARY my_dict ( StopWords = newrussian );
51
52
53 The following example command changes the language option to dutch, and
54 removes the stopword option entirely.
55
56 ALTER TEXT SEARCH DICTIONARY my_dict ( language = dutch, StopWords );
57
58
59 The following example command ``updates'' the dictionary's definition
60 without actually changing anything.
61
62 ALTER TEXT SEARCH DICTIONARY my_dict ( dummy );
63
64 (The reason this works is that the option removal code doesn't complain
65 if there is no such option.) This trick is useful when changing config‐
66 uration files for the dictionary: the ALTER will force existing data‐
67 base sessions to re-read the configuration files, which otherwise they
68 would never do if they had read them earlier.
