Can anyone share what value they have set log_min_duration_statement to?
It's OT but we use different values for different databases and needs. On a very loaded database with a lot of complex queries (lots of join on big tables, proximity queries, full text queries), we use 100 ms. It logs ~ 300 000 queries. It allows us to detect big regressions or new queries which are very slow. On another database where I want to track transaction leaks, I'm forced to put it to 0ms. Basically, the answer is: set it to the lowest value you can afford without impacting too much your performances (and if you use syslog, use async I/O or send your log to the network). -- Guillaume
