Original advisory details:

 Michael Fuhr discovered an incorrect type check when handling unknown
 literals. By attempting to coerce such a literal to the ANYARRAY type,
 a local authenticated attacker could cause a server crash. (CVE-2006-5541)

 Josh Drake and Alvaro Herrera reported a crash when using aggregate
 functions in UPDATE statements. A local authenticated attacker could
 exploit this to crash the server backend. This update disables this
 construct, since it is not very well defined and forbidden by the SQL
 standard. (CVE-2006-5540)

 Sergey Koposov discovered a flaw in the duration logging. This could
 cause a server crash under certain circumstances. (CVE-2006-5542)

 Please note that these flaws can usually not be exploited through web
 and other applications that use a database and are exposed to
 untrusted input, so these flaws do not pose a threat in usual setups.");
