Attached is the patch to save you a few key strokes :)

Considering this as a bug-fix, I'd vote for it to be applied to all
supported releases. But since this may cause unforeseen performance
penalty, I think it should be applied only as far back as the
introduction of PGSTAT_STAT_INTERVAL throttle.
The throttle was implemeted in 641912b, which AFAICT was part of 8.3.
So I guess all the supported releases it is.
