postgresql-8.4 (8.4.7-0ubuntu0.9.10) karmic-security; urgency=low

  * New upstream security/bug fix release: (LP: #711318)
    - Fix buffer overrun in "contrib/intarray"'s input function for the
      query_int type.
      This bug is a security risk since the function's return address
      could be overwritten. Thanks to Apple Inc's security team for
      reporting this issue and supplying the fix. (CVE-2010-4015)
    - Avoid failures when "EXPLAIN" tries to display a simple-form CASE
      expression.
      If the CASE's test expression was a constant, the planner could
      simplify the CASE into a form that confused the expression-display
      code, resulting in "unexpected CASE WHEN clause" errors.
    - Fix assignment to an array slice that is before the existing range
      of subscripts.
      If there was a gap between the newly added subscripts and the first
      pre-existing subscript, the code miscalculated how many entries
      needed to be copied from the old array's null bitmap, potentially
      leading to data corruption or crash.
    - Avoid unexpected conversion overflow in planner for very distant
      date values.
      The date type supports a wider range of dates than can be
      represented by the timestamp types, but the planner assumed it
      could always convert a date to timestamp with impunity.
    - Fix pg_restore's text output for large objects (BLOBs) when
      standard_conforming_strings is on.
      Although restoring directly to a database worked correctly, string
      escaping was incorrect if pg_restore was asked for SQL text output
      and standard_conforming_strings had been enabled in the source
      database.
    - Fix erroneous parsing of tsquery values containing ... &
      !(subexpression) | ... .
      Queries containing this combination of operators were not executed
      correctly. The same error existed in "contrib/intarray"'s query_int
      type and "contrib/ltree"'s ltxtquery type.
    - Fix bug in "contrib/seg"'s GiST picksplit algorithm.
      This could result in considerable inefficiency, though not actually
      incorrect answers, in a GiST index on a seg column. If you have
      such an index, consider "REINDEX"ing it after installing this
      update. (This is identical to the bug that was fixed in
      "contrib/cube" in the previous update.)
