The problem is that "LIMIT 1 OFFSET 0" has such poor performance. I'm
not so much worried about the query time (it's still low enough to be
acceptable), but the fact that it behaves oddly raised the question of
whether this was correct behaviour or not. I'll try it with a saner
value for effective_cache_size.
