Sorry if I gave the impression earlier that we should get rid of hash
indexes because there might be more bugs. I didn't really mean it that
way. I just meant that if this one was going to be a hard fix, then that
might be one of the mitigating factors for how much work someone's going
to be willing to put into this.
If it's an easy fix then it's likely worth the effort to keep the hash
indexes around.
