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.

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.
