Hello thanks for the answers. But nothing matches my problem. I read the manual again and decide me for an other way. I change my table that it looks like: lang | text ---------------------- german | hallo welt english | hello world Then i follow the manual which says: http://www.postgresql.org/docs/8.3/interactive/textsearch- tables.html#TEXTSEARCH-TABLES-INDEX It is possible to set up more complex expression indexes wherein the configuration name is specified by another column, e.g.: CREATE INDEX pgweb_idx ON pgweb USING gin(to_tsvector(config_name, body)); It is possible to set up more complex expression indexes wherein the configuration name is specified by another column, e.g.: I did a CREATE INDEX idx ON test.test1 USING gin(to_tsvector(lang, "text")); and CREATE INDEX idx ON test.test1 USING gin(to_tsvector(lang::regconfig, "text")); For both I get this error in german: FEHLER: Funktionen im Indexausdruck müssen als IMMUTABLE markiert sein SQL state: 42P17 means in english functions in index expression must be marked IMMUTABLE Now I have no idea. My experience with databases and postgresql are too less to decide if this is a bug, or myself is the bug ;-).
