No, actually I haven't yet. I have noticed that during the time the query executes there is neither so much CPU load nor network (communication with db) load. The client seems to hang, then after a minute or so the query returns data. I also thought this problem could be related to db encoding but changing it didn't help at all. If it's a client-related problem, I can't understand why such different clients behave the same way Regards Massimo ---------------------------(end of broadcast)--------------------------- TIP 7: You can help support the PostgreSQL project by donating at http://www.postgresql.org/about/donate
