Setting this to zero prints all statement durations. Minus-one (the default) disables logging statement durations. For example, if you set it to 250ms then all SQL statements that run 250ms or longer will be logged. Enabling this parameter can be helpful in tracking down unoptimized queries in your applications. Only superusers can change this setting. On 02/23/2017 09:21 AM, Dinesh Chandra 12108 wrote: Dear expert, I want to log only that queries which are taking around 5 minutes to execute.
