It was discovered that the TCL regular expression parser used
by PostgreSQL did not properly check its input. An attacker
could send crafted regular expressions to PostgreSQL and cause
a denial of service via resource exhaustion or database crash.
(CVE-2007-4769, CVE-2007-4772, CVE-2007-6067)

It was discovered that PostgreSQL executed VACUUM and ANALYZE
operations within index functions with superuser privileges and
also allowed SET ROLE and SET SESSION AUTHORIZATION within index
functions. A remote authenticated user could exploit these flaws
to gain privileges. (CVE-2007-6600)");
