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. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
