http://bugs.debian.org/697618
[ Martin Pitt ]
* Add autopkgtest, moved from postgresql-common.
* debian/rules: Only build the error codes and the plpython subtree for the
  "python3" flavor, to cut down build time.
* Add missing docbook build dependency. (Closes: #697618)

[ Christoph Berg ]
* New upstream version.
  + Prevent execution of enum_recv from SQL
    The function was misdeclared, allowing a simple SQL command to crash the
    server.  In principle an attacker might be able to use it to examine the
    contents of server memory.  Our thanks to Sumit Soni (via Secunia SVCRP)
    for reporting this issue. (CVE-2013-0255)
