I saw that recently while hacking around, but I thought it was because of stuff I'd added. But apparently not. Hm. I think I see how that might happen. It might be possible (and harmless) if two subxacts of the same toplevel xact have the same first_lsn. But if it's not just <= vs < it'd be worse. > Unfortunately I don't have a core file and I haven't been able to reproduce > this. Any information about the workload? Any chance you still have the data directory around?
