Log message:
This release fixes a number of issues reported by users over the last two \ 
months. Most database administrators should plan to upgrade at the next \ 
available downtime, unless they have been affected directly by the fixed issues.

Log message:
The PostgreSQL Global Development Group has released an update to all supported \ 
versions of our database system, including 9.5.2, 9.4.7, 9.3.12, 9.2.16, and \ 
9.1.21. This release fixes two security issues and one index corruption issue in \ 
version 9.5. It also contains a variety of bug fixes for earlier versions. Users \ 
of PostgreSQL 9.5.0 or 9.5.1 should update as soon as possible.

This release closes security hole CVE-2016-2193, where a query plan might get \ 
reused for more than one ROLE in the same session. This could cause the wrong \ 
set of Row Level Security (RLS) policies to be used for the query.

The update also fixes CVE-2016-3065, a server crash bug triggered by using \ 
pageinspect with BRIN index pages. Since an attacker might be able to expose a \ 
few bytes of server memory, this crash is being treated as a security issue.
