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(at)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

        !       Local  blocks:          0 read,          0 written, 
buffer hit rate = 0.00%
        !       Direct blocks:          0 read,          0 written


Am I missing something obvious?
