Yes, it can be a bit verbose, but I don't think it's that verbose. I'm one
of those this information about checkpoint progress may be a valuable info
- even on production systems - that's why I don't want to put that into
the debug levels.
It should write about 10 lines for each checkpoint (altough I've just
realized the current patch won't do that for the timed checkpoints - it'll
probably log significantly more).
My 'ideal' solution would be either to add another GUC (to turn this
on/off) or allow log_checkpoints to have three values
log_checkpoints = {off, normal, detailed}
where 'normal' provides the current output and 'detail' produces this much
verbose output.
