I keep seeing the following log output around every 5 minutes: 2005-02-28 23:25:05 [8646] LOG: 00000: QUERY STATISTICS DETAIL: ! system usage stats: ! 0.005023 elapsed 0.000000 user 0.000000 system sec !

The server is postgresql 7.4, running on debian linux. According to postgres.c, it should be outputting due to GUC, however I verified that all of the log_*_stats lines in the postgresql.conf are turned off and also verified those GUC's are off in the show all; output... here's the relevant bits. log_connections | off log_duration | off log_error_verbosity | verbose log_executor_stats | off log_hostname | off log_min_duration_statement | 5000 log_min_error_statement | info log_min_messages | notice log_parser_stats | off log_pid | on log_planner_stats | off log_source_port | off log_statement | off log_statement_stats | off log_timestamp | on the only thing real sketchy about this is that it always seems to be on the same pid (8646) and if I turn query logging on I see the following executed right before this happens: 2005-03-01 00:25:08 [8646] LOG: 00000: statement: select "_rv".cleanupEvent(); LOCATION: pg_parse_query, postgres.c:464 now according to the slony folks, there is nothing in slony that modifys the logging output... so assuming that's true, anyone have any ideas on what might be causing this logging? -- Robert Treat Build A Brighter Lamp :: Linux Apache {middleware} PostgreSQL ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
