Logging statement/duration on the same line

I'm writing a log parser front-end. I've seen some log samples that
look like this, with the duration and statement on the same line:

LOG: duration: 1.565 ms statement: SELECT * FROM users WHERE user_id='692'

But in my 8.3.9 test installation, durations are always logged on a
separate line. Is the sample above from a different version? Or is
there a way to get this output with different configuration? Here's
the type of output that I see in 8.3.9:

2010-02-08 15:31:50.872 EST LOG: statement: select 1;
2010-02-08 15:31:50.881 EST LOG: duration: 10.870 ms
