Update postgresql to 9.2.15 (CVE-2016-0773)
To address CVE-2016-0773, update postgresql to 9.2.15.
This release closes security hole CVE-2016-0773, an issue with regular expression (regex) parsing. Prior code allowed users to pass in expressions which included out-of-range Unicode characters, triggering a backend crash. This issue is critical for PostgreSQL systems with untrusted users or which generate regexes based on user input.
