Обсуждение: little correction

Bruce,

I think 
ALTER TEXT SEARCH CONFIGURATION russian    ADD MAPPING FOR asciiword, asciihword, hword_asciipart WITH
thesaurus_simple;

should be 
ALTER TEXT SEARCH CONFIGURATION russian    ALTER MAPPING FOR asciiword, asciihword, hword_asciipart WITH
thesaurus_simple;

since configuration russian already exists.

    Regards,        Oleg

Done.  I notice that if you try to do it the other way, you get:

regression=# ALTER TEXT SEARCH CONFIGURATION russian    ADD MAPPING FOR asciiword, asciihword, hword_asciipart WITH
simple;
ERROR:  duplicate key value violates unique constraint "pg_ts_config_map_index"

This is not very good --- we usually try to provide a more friendly
error message than "unique constraint violation" for duplicate system
catalog entries.  Not sure how hard it is to fix.
