Hmph. That seems to eliminate the overflow theory, because 8.2 has
essentially the same lock-counting code as 8.3. Unless 8.3 is taking
out the lock a heckuva lot more than 8.2 did, but I can't think of a
reason for that to happen.
Now that we know you can reproduce it, we should think about how to get
some information out. Are you in a position to build a locally modified
Postgres? I could send you a patch to make that particular error report
dump out more information about the lock state, but a patch won't do you
any good if you aren't able to build from source.
