Ensure 'log_statement_stats' is disabled


The logging of these additional statistics when not mandated by your organization's logging policy greatly reduces the signal-to-noise ratio of the PostgreSQL logs.


Enabling the log_statement_stats setting causes cumulative performance statistics to be written to the server log for each query. This is a crude profiling instrument, similar to the Unix getrusage() operating system facility.

This reports total statement statistics. Cumulative performance statistics logging is disabled (off) by default and should only be enabled if directed to do so by your organization's logging policy.

Note: log_statement_stats cannot be enabled together with any of the per-module options.
