Updated postgresql packages fix security vulnerabilities

Updated postgresql packages fix security vulnerabilities: A user with limited clearance on a table might have access to information in columns without SELECT rights on through server error messages (CVE-2014-8161). The function to_char() might read/write past the end of a buffer. This might crash the server when a formatting template is processed (CVE-2015-0241). The pgcrypto module is vulnerable to stack buffer overrun that might crash the server (CVE-2015-0243). Emil Lenngren reported that an attacker can inject SQL commands when the synchronization between client and server is lost (CVE-2015-0244). This update provides PostgreSQL versions 9.3.6, 9.2.10, 9.1.15, and 9.0.19 that fix these issues, as well as several others.
