Two security issues have been fixed in this release which affect users
of specific PostgreSQL features:
CVE-2015-5289: json or jsonb input values constructed from arbitrary
user input can crash the PostgreSQL server and cause a denial of
service.
CVE-2015-5288: The crypt( function included with the optional pgCrypto
extension could be exploited to read a few additional bytes of memory.
No working exploit for this issue has been developed.
This update will also disable SSL renegotiation by default;
previously, it was enabled by default. SSL renegotiation will be
removed entirely in PostgreSQL versions 9.5 and later.

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.

The update is mostly to fix the file persmission problem described
in the URL below. You might want to wait until next upgrade, depending
on you local configuration.

Data Corruption Fix
For users of PostgreSQL versions 9.3 or 9.4, this release fixes a problem where
the database will fail to protect against "multixact wraparound", resulting in
data corruption or loss. Users with a high transaction rate (1 million or more
per hour) in a database with many foreign keys are especially vulnerable. We
strongly urge all users of 9.4 and 9.3 to update their installations in the
next few days.
Users of versions 9.2 and earlier are not affected by this issue.

This update fixes multiple security issues reported in PostgreSQL over the past
few months. All of these issues require prior authentication, and some require
additional conditions, and as such are not considered generally urgent.
However, users should examine the list of security holes patched below in case
they are particularly vulnerable.

uuid-ossp patch has been outdated with irrelevant changes (for us),
so massage back in.
In head of postgresql, this is handled properly, so eventually the ossp patches
can go.
version of the database system, including versions 9.3.4, 9.2.8, 9.1.13,
9.0.17, and 8.4.21. This minor release fixes a data corruption issue with
replication and crash recovery in version 9.3, as well as several other minor
issues in all versions. All users of version 9.3 are urged to update their
installations at the next possible downtime. Users of older versions should
update at their convenience.
The data corruption issue in PostgreSQL 9.3 affects binary replication
standbys, servers being recovered from point-in-time-recovery backup, and
standalone servers which recover from a system crash. The bug causes
unrecoverable index corruption during recovery due to incorrect replay of row
locking operations. This can then cause query results to be inconsistent
depending on whether or not an index is used, and eventually lead to primary
key violations and similar issues. For this reason, users are encouraged to
replace each of their standby databases with a new base backup after applying
the update.

A change specific to the FreeBSD port:
Modify the contrib/uuid-ossp to actually work (not crashing the backend) by
using the libc implementation of uuid instead of the ossp port. Schemas and
queries will just work. Based on the work of Andrew Gierth. 9.1+ EXTENSION
support added by girgen@.

update to all supported versions of the PostgreSQL database system,
which includes minor versions 9.3.3, 9.2.7, 9.1.12, 9.0.16, and
8.4.20. This update contains fixes for multiple security issues, as
well as several fixes for replication and data integrity issues. All
users are urged to update their installations at the earliest
opportunity, especially those using binary replication or running a
high-security application.
This update fixes CVE-2014-0060, in which PostgreSQL did not properly
enforce the WITH ADMIN OPTION permission for ROLE management. Before
this fix, any member of a ROLE was able to grant others access to the
same ROLE regardless if the member was given the WITH ADMIN OPTION
permission. It also fixes multiple privilege escalation issues,
including: CVE-2014-0061, CVE-2014-0062, CVE-2014-0063, CVE-2014-0064,
CVE-2014-0065, and CVE-2014-0066. More information on these issues can
be found on our security page and the security issue detail wiki page.

to all supported versions of the PostgreSQL database system, which
includes minor versions 9.3.2, 9.2.6, 9.1.11, 9.0.15, and 8.4.19. This
update fixes three serious data-loss bugs affecting replication and
database maintenance. All users are urged to update their
installations at the earliest opportunity.

Note that users of the hstore extension on version 9.3 must take an additional,
post upgrade step of running "ALTER EXTENSION hstore UPDATE" in each database
after update.

Major enhancements in PostgreSQL 9.3 include:
- Add materialized views
- Make simple views auto-updatable
- Add many features for the JSON data type, including operators and functions to extract elements from JSON values
- Implement SQL-standard LATERAL option for FROM-clause subqueries and function calls
- Allow foreign data wrappers to support writes (inserts/updates/deletes) on foreign tables
- Add a Postgres foreign data wrapper to allow access to other Postgres servers
- Add support for event triggers
- Add optional ability to checksum data pages and report corruption
- Prevent non-key-field row updates from blocking foreign key checks
- Greatly reduce System V shared memory requirements
