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).
