Well, considering that the parse and bind may take longer than the
execute, I hardly think we want to ignore them for log_duration
purposes.  And we agreed that if log_duration is on and
log_min_duration_statement is not triggered, log_duration should print
*only* duration.  So I'm not sure what else you expected.
