Further update on this:

We've isolated this issue to JDBC client access.
When connecting using the latest JDBC driver, we do not get "Duration:"
LOG messages when using log_duration = true.
[driver 8.0-310.jdbc2.jar]

We've tested both localhost connections and remotely connected users
with libpq clients and these do produce the log records for the
"Duration:" as we would expect.

Is this a V2/V3 protocol issue? Or a bug? (If so, where)

Thanks for any help.

Best Regards, Simon Riggs
