Hi,
I am testing version 9.1.9 before putting it in production. One of my tests involved deleting a the contents of a big table ( ~ 13 GB size) and then VACUUMing it. During VACUUM PANICS. Here is the message:
PANIC: corrupted item pointer: offset = 8128, size = 80
I found the error a couple of times, allways during VACUUM after deleting the context of the same big table (after re-polpulating it of course).
The error message is always *exactly* the same i.e. the same offset and size.
When this happens the backend gets restarted and if I issue the same VACUUM command, I get the same error.
I also tried triggering the backup server (hot-standby with streaming replication, and trying the VACUUM there (to see if it may be a hardware problem in the primary) and got the same issue.
What might be causing this? Should I reported as a bug? Thanks!
