Comment 20 for bug 1088393

This bug was fixed in the package postgresql-9.1 - 9.1.7-0ubuntu11.10

---------------
postgresql-9.1 (9.1.7-0ubuntu11.10) oneiric-proposed; urgency=low

  * New upstream bug fix release: (LP: #1088393)
    - Fix multiple bugs associated with "CREATE INDEX CONCURRENTLY".
      Fix "CREATE INDEX CONCURRENTLY" to use in-place updates when
      changing the state of an index's pg_index row. This prevents race
      conditions that could cause concurrent sessions to miss updating
      the target index, thus resulting in corrupt concurrently-created
      indexes.
      Also, fix various other operations to ensure that they ignore
      invalid indexes resulting from a failed "CREATE INDEX CONCURRENTLY"
      command. The most important of these is "VACUUM", because an
      auto-vacuum could easily be launched on the table before corrective
      action can be taken to fix or remove the invalid index.
    - Fix buffer locking during WAL replay.
      The WAL replay code was insufficiently careful about locking
      buffers when replaying WAL records that affect more than one page.
      This could result in hot standby queries transiently seeing
      inconsistent states, resulting in wrong answers or unexpected
      failures.
    - See HISTORY/changelog.gz for the other bug fixes.
