"Still" meaning "in the version he's using", which he hasn't told us
anywhere that I saw. (Internal evidence suggests it's 7.3 something)

A deadlock in hash indexes wouldn't be surprising in pre-7.4 code,
since 7.4 was the first version that even pretended to be deadlock free
in hash indexes. But it does seem pretty surprising that the deadlock
checker didn't fire and boot somebody out of the deadlock. We haven't
had any bugs reported in deadlock detection in a very long time (since
7.1 I think). This could mean there's still something wrong in there.
