Hi
I want to have postgres log sql statements that take longer than 5
seconds to execute. In postgresql.conf I have set
log_min_duration_statement as follows:
root@martin-desktop:/etc/postgresql/8.3/main# grep log_min_duration
postgresql.conf
log_min_duration_statement = 5000 # -1 is disabled, 0 logs all
statements
However, in the log files, I'm seeing entries for all SQL executed, not
just that taking 5000ms or more. For example:
2008-10-14 10:15:50 BST PID:20349 DB:vhdb LOG: statement: select * from
vendors;
2008-10-14 10:15:50 BST PID:20349 DB:vhdb LOG: duration: 0.259 ms
2008-10-14 10:15:50 BST PID:20349 DB:vhdb LOG: QUERY STATISTICS
2008-10-14 10:15:50 BST PID:20349 DB:vhdb DETAIL: ! system usage stats:

Am I missing something obvious?
Regards
