Hello,

I am currently writing some curriculum on managing IO with PostgreSQL and I keep running into the parameter checkpolint_timeout.
*cough* checkpoint_timeout

  This seems to
be incorrect as it is not really a timeout as much as an interval...

It is a timeout because of WAL fills up before the timeout you get a
checkpoint and the timer is reset.  How is it an interval?

because if it doesn't, it will checkpoint at that timeout which is an interval :). It depends on how you look at it I guess. For me, I try to make sure we are never rolling our logs until checkpoint, so it is an interval.
