Hi,



This database has not had the same failure again 2019/09/16(reported at 2019/09/29), so this is a very low probability failure, but it is uncertain whether it will happen again in the future. Now add some information for incident at 2019/09/16, may be useful for analyze the cause of this problem.

According to above information, the flags of the heap page (163363) with the problem tuple (163363, 9) is 0x0001 (HAS_FREE_LINES), that is, ALL_VISIBLE is not set.


However, according  hexdump content of the corresponding vm file, that block(location is 9F88 + 6bit) has set VISIBILITYMAP_ALL_FROZEN and VISIBILITYMAP_ALL_VISIBLE flags. That is, the heap file and the vm file are inconsistent.

That's not supposed to happen, and represents data corruption. Your
previous report of a too-old xmin surviving in the heap is also
corruption.  There is no guarantee that both problems have the same
cause, but suppose they do. One possibility is that a write to the
heap page may have gotten lost or undone. Suppose that, while this
page was in shared_buffers, VACUUM came through and froze it, setting
the bits in the VM and later truncating CLOG. Then, suppose that when
that page was evicted from shared_buffers, it didn't really get
written back to disk, or alternatively it did, but then later somehow
the old version reappeared. I think that would produce these symptoms.

I think that bad hardware could cause this, or running two copies of
the server on the same data files at the same time, or maybe some kind
of filesystem-related flakiness, especially if, for example, you are
using a network filesystem like NFS, or maybe a broken iSCSI stack.
There is also no reason it couldn't be a bug in PostgreSQL itself,
although if we lost page writes routinely somebody would surely have
noticed by now.

The value is only needed by te worker, so there is no need to store it in
shared memory.
