Updated postgresql packages fix security vulnerabilities:
PostgreSQL 9.3.x before 9.3.11 and 9.4.x before 9.4.6 does not properly restrict access to unspecified custom configuration settings (GUCS) for PL/Java, which allows attackers to gain privileges via unspecified vectors (CVE-2016-0766).
PostgreSQL 9.3.x before 9.3.11 and 9.4.x before 9.4.6 allows remote attackers to cause a denial of service (infinite loop or buffer overflow and crash) via a large Unicode character range in a regular expression (CVE-2016-0773).
