You can (and should) set log_min_duration_statement, maybe to 1000 (1000ms), and observe the log. Read our docu about EXPLAIN, and analyse long-running queries with EXPLAIN (ANALYSE). And again, performance tuning depends on the real workload on the server, it's hard to give you a recipe for all use-cases. Andreas -- Really, I'm not out to destroy Microsoft.
