4.8.2 Statistics Monitoring

log_statement_stats (boolean)

log_parser_stats (boolean)

log_planner_stats (boolean)

log_executor_stats (boolean)

For each query, write performance statistics of the respective module to the server log. This is a crude profiling instrument. log_statement_stats reports total statement statistics, while the others report per-module statistics. log_statement_stats cannot be enabled together with any of the per-module options. All of these options are disabled by default. Only superusers can change these settings.
