Hello, in the documentation is written that there'a a perfomrance impact if another locale than C or POSIX is used. problem is that using the standard locale results in unusable order results for languages with spcial chars. in my example "umlauts" in german. it isn't acceptable to use the database without indexes if another locale is used. are custom operator classes as described in the manual as high-performance as the native index? are there any examples how to use them in my case? are there any tests that show how the performance decreases if another locale is used? why is there a perfomance impact? it's a disappointing that postgresql is only in one configuration to suply the max. performance. any tips or hints on that? regards Daniel ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
