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.

This release primarily fixes issues not successfully fixed in prior releases. It should be applied as soon as possible all users of major versions 9.3 and 9.4. Other users should apply at the next available downtime.
Crash Recovery Fixes:
Earlier update releases attempted to fix an issue in PostgreSQL 9.3 and 9.4 with "multixact wraparound", but failed to account for issues doing multixact cleanup during crash recovery. This could cause servers to be unable to restart after a crash. As such, all users of 9.3 and 9.4 should apply this update as soon as possible.

supported version of the database system, including versions 9.3.5, 9.2.9, 9.1.14, 9.0.18, and 8.4.22. This minor release fixes a number of issues discovered and reported by users over the last four months, including some data corruption issues, and is the last update of version 8.4. Users of version 9.3 will want to update at the earliest opportunity; users of version 8.4 will want to schedule an upgrade to a supported PostgreSQL version.

Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.
