Thanks for the input.

We'll upgrade to 9.2.10 and attempt to reproduce the issue.

If possible, can someone point to corruption related issues fixed after 9.2.0?

Thanks,
-Bankim.

    Hello postgres experts,

    We are running a test that periodically abruptly kills postgres
    process(equivalent to kill -9) and restarts it.
    After running this test for 24 hrs or so, we see duplicate primary
    key entries in postgres table.

    We detect this as we load internal hash-table data-structure in a
    separate process with primary key entries.

    Before hitting this issue we see following warning messages in pg_log

    17365 2015-03-24 03:01:42.729 GMTWARNING:  page is not marked
    all-visible but visibility map bit is set in relation "table_foo"
    page 12

    Some information about postgres setup.
    - 9.2.0
    - We use standard configuration with shared_buffer setting as 32MB
    and checkpoint_timeout as 1 min.
    - In this particular case postgres replication is not enabled.

    Let me know if more information is needed to help understand this
    issue.

    Any help or pointers will be appreciated.


If you really are running 9.2.0 instead of 9.2.10 you should upgrade and reconfirm.
