  postgresql-9.5 (9.5.16-0ubuntu0.16.04.1) xenial; urgency=medium

  * New upstream release(s) (LP: #1815665)
    - By default, panic instead of retrying after fsync() failure, to avoid
      possible data corruption. A new server parameter "guc-data-sync-retry"
      has been added to control this;
    - d/p/pg-9.5-Disallow-setting-client_min_messages-higher-than-ERR.patch:
      to retain SRU stability this patch reverts one of the changes which
      disabled the error suppression by setting client_min_messages to
      fatal or panic. Overall that means no change to the handling of
      client_min_messages due to this upload.

  postgresql-9.5 (9.5.14-0ubuntu0.16.04) xenial-security; urgency=medium

  * New upstream release (LP: #1786938)
    - Fix failure to reset libpq's state fully between connection attempts
      .
      An unprivileged user of dblink or postgres_fdw could bypass the checks
      intended to prevent use of server-side credentials, such as a ~/.pgpass
      file owned by the operating-system user running the server. Servers
      allowing peer authentication on local connections are particularly
      vulnerable. Other attacks such as SQL injection into a postgres_fdw
      session are also possible. Attacking postgres_fdw in this way requires
      the ability to create a foreign server object with selected connection
      parameters, but any user with access to dblink could exploit the
      problem. In general, an attacker with the ability to select the
      connection parameters for a libpq-using application could cause
      mischief, though other plausible attack scenarios are harder to think
      of. Our thanks to Andrew Krasichkov for reporting this issue.
      (CVE-2018-10915)
    - Fix INSERT ... ON CONFLICT UPDATE through a view that isn't just SELECT
      FROM ...
      .
      Erroneous expansion of an updatable view could lead to crashes or
      attribute ... has the wrong type errors, if the view's SELECT list
      doesn't match one-to-one with the underlying table's columns.
      Furthermore, this bug could be leveraged to allow updates of columns
      that an attacking user lacks UPDATE privilege for, if that user has
      INSERT and UPDATE privileges for some other column(s) of the table. Any
      user could also use it for disclosure of server memory.
      (CVE-2018-10925)
    - d/libecpg-dev.install: Add new pgtypes header.
    - d/libpgtypes3.symbols: Add new pgtypes symbol.

  * New upstream release (LP: #1769888)
    - A dump/restore is not required for those running 9.5.X.
      However, if the function marking mistakes mentioned in the first
      changelog entry affect you, you will want to take steps to
      correct your database catalogs.
