Re: Use case for enabling log_duration other than benchmarking

Do you know any use case for enabling log_duration? Like 3rd party tools for instance.

I find this parameter pretty much useless (in opposite to log_min_duration_statement) as it does not show the query text, so besides having just the timing logged it is of no use in troubleshooting and often causes huge overhead. Am I missing something?

Note

The difference between enabling log_duration and setting log_min_duration_statement to zero is that exceeding log_min_duration_statement forces the text of the query to be logged, but this option doesn't. Thus, if log_duration is on and log_min_duration_statement has a positive value, all durations are logged but the query text is included only for statements exceeding the threshold. This behavior can be useful for gathering statistics in high-load installations.
