Thank you Matheus!
Based on the study, there's very little performance impact when enabling log_min_duration_statement, right?
Thank you

POWA authors even did a comparison of performance impact of having log_min_duration_statement (to latter process with pgBadger), using POWA extension and nothing, see [3].
