Mmm ... I don't think so, since AFAICT that message string is not present in 8.1.5. Please recheck the server version. If you can put together a reproducible test case for this, we should be able to fix it, but right now there's not enough info available to guess what's going wrong. FWIW, I imagine that a test case would involve a specific sequence of data inserted into a hash index. regards, tom lane
