The thing is, you shouldn't ever get "out of free buffers", period.
Jeffrey must be running into some kind of buffer-leak bug ... but it's
hard to think what, unless he's running an extremely old PG version.
We haven't seen reports of buffer leaks in a long time. So I'd like
to run that down, quite independently of whether he should change his
query for efficiency.
