Thanks for clarifying it. The user-visible behavior, as I understand it,
is that the time between archiving on an idle database is:
MAX(archive_timeout,checkpoint_timeout)
[ of course, there's no guarantee that the archive_command succeeds in
that time ]
It looks like checkpoint_timeout was the limiting factor, in his case.
