Hi Claudio - you don't want the hackers list, you probably want the performance list. You will want to do the following first: 1. VACUUM ANALYZE the tables used by the view. 2. Provide the output of EXPLAIN ANALYSE SELECT * FROM myview; 3. Provide the definitions of the tables used, and how many rows are in each table. I'll see you on the performance list, and we'll see if we can't help you this afternoon. -- Richard Huxton Archonet Ltd ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
