postgresql-9.5 (9.5.5-0ubuntu0.16.10) yakkety; urgency=medium

  * New upstream bug fix release (LP: #1637236)
    - Fix WAL-logging of truncation of relation free space maps and visibility
      maps.
      It was possible for these files to not be correctly restored during
      crash recovery, or to be written incorrectly on a standby server. Bogus
      entries in a free space map could lead to attempts to access pages that
      have been truncated away from the relation itself, typically producing
      errors like "could not read block XXX: read only 0 of 8192 bytes".
      Checksum failures in the visibility map are also possible, if
      checksumming is enabled.

      Procedures for determining whether there is a problem and repairing it
      if so are discussed at
         https://wiki.postgresql.org/wiki/Free_Space_Map_Problems.
