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.
This update fixes CVE-2014-0060, in which PostgreSQL did not properly enforce the WITH ADMIN OPTION permission for ROLE management.

c) have any dependency on any p5-* package
Like last time, where this caused no complaints.
The security issue fixed in this release, CVE-2013-0255, allows a previously authenticated user to crash the server by calling an internal function with invalid arguments. This issue was discovered by independent security researcher Sumit Soni this week and reported via Secunia SVCRP, and we are grateful for their efforts in making PostgreSQL more secure.
Today's update also fixes a performance regression which caused a decrease in throughput when using dynamic queries in stored procedures in version 9.2. Applications which use PL/pgSQL's EXECUTE are strongly affected by this regression and should be updated. Additionally, we have fixed intermittent crashes caused by CREATE/DROP INDEX CONCURRENTLY, and multiple minor issues with replication.
This release is expected to be the final update for version 8.3, which is now End-of-Life (EOL). Users of version 8.3 should plan to upgrade to a later version of PostgreSQL immediately. For more information, see our Versioning Policy.
This update release also contains fixes for many minor issues discovered and patched by the PostgreSQL community in the last two months, including:
* Prevent unnecessary table scans during vacuuming
* Prevent spurious cached plan error in PL/pgSQL
* Allow sub-SELECTs to be subscripted
* Prevent DROP OWNED from dropping databases or tablespaces
* Make ECPG use translated messages
* Allow PL/Python to use multi-table trigger functions (again) in 9.1 and 9.2
* Fix several activity log management issues on Windows
* Prevent autovacuum file truncation from being cancelled by deadlock_timeout
* Make extensions build with the .exe suffix automatically on Windows
* Fix concurrency issues with CREATE/DROP DATABASE
* Reject out-of-range values in to_date() conversion function
* Revert cost estimation for large indexes back to pre-9.2 behavior
* Make pg_basebackup tolerate timeline switches
* Cleanup leftover temp table entries during crash recovery
* Prevent infinite loop when COPY inserts a large tuple into a table with a large fillfactor
* Prevent integer overflow in dynahash creation
* Make pg_upgrade work with INVALID indexes
* Fix bugs in TYPE privileges
* Allow Contrib installchecks to run in their own databases
* Many documentation updates
* Add new timezone "FET".
The update fixes two potential data corruption issues present in the PostgreSQL 9.1 and 9.2 for any server which has crashed, been shutdown with "immediate", or was failed over to a standby. First, the PostgreSQL development team has discovered a chance of corruption of BTREE and GIN indexes for databases. Second, there is a significant chance of corruption of the visibility map. This update fixes both issues.
We strongly advise users of 9.1 and 9.2 to run VACUUM and/or index rebuilds after applying the update. Please see the 2012-09-24 Update wiki page for detailed instructions.
This update release also contains fixes for many minor issues discovered and patched by the PostgreSQL community in the last month, including many fixes for the newly released version 9.2. These include:
fix sorting issue with IN lists and indexes
fix planner failure when combining GROUP BY with window functions
improve selectivity of text searches using prefixes
prevent rescanning of WITH clauses from giving wrong answers
fix PL/Perl crashing issue
reduce bloat for multi-column GiST indexes
time zone data changes for Fiji
disallow Extensions from circular schema assignment
prevent crashes when default_transaction_isolation is set to "serializable"

The list of packages is computed by finding all packages which end
up having either of PERL5_USE_PACKLIST, BUILDLINK_API_DEPENDS.perl,
or PERL5_PACKLIST defined in their make setup (tested via
"make show-vars VARNAMES=..."), minus the packages updated after
the perl package update.

fractional byte correctly when the output bit width is wider than
the given integer by something other than a multiple of 8 bits

in particular make it possible to exclude a partition that has a
"bool_column = false" constraint

This is more useful than before and helps to prevent confusion when
a "REVOKE" generates multiple messages, which formerly appeared to
be duplicates.
* When reading "pg_hba.conf" and related files, do not treat
@something as a file inclusion request if the @ appears inside
quote marks; also, never treat @ by itself as a file inclusion
request
* Prevent infinite loop on some platforms if a directory is named as
an inclusion target in "pg_hba.conf" and related files
* Fix possible infinite loop if SSL_read or SSL_write fails without
setting errno
This is reportedly possible with some Windows versions of openssl.

--single-transaction are both specified and an error occurs during
the implied "COMMIT"
* Fix pg_dump's output of permissions for foreign servers
* Fix possible crash in parallel pg_restore due to out-of-range
dependency IDs

* Fix possible failure when calling PL/Perl functions from PL/PerlU
or vice versa

The only known symptom of this oversight is that the Tcl clock
command misbehaves if using Tcl 8.5 or later.
* Prevent ExecutorEnd from being run on portals created within a
failed transaction or subtransaction
This is known to cause issues when using "contrib/auto_explain".
* Prevent crash in "contrib/dblink" when too many key columns are
specified to a dblink_build_sql_* function
* Allow zero-dimensional arrays in "contrib/ltree" operations
* Fix assorted crashes in "contrib/xml2" caused by sloppy memory
management
* Make building of "contrib/xml2" more robust on Windows
* Fix race condition in Windows signal handling
One known symptom of this bug is that rows in pg_listener could be
dropped under heavy load.
* Make the configure script report failure if the C compiler does not
provide a working 64-bit integer datatype
This case has been broken for some time, and no longer seems worth
supporting, so just reject it at configure time instead.
* Update time zone data files to tzdata release 2010e for DST law
changes in Bangladesh, Chile, Fiji, Mexico, Paraguay, Samoa.
* Fix WAL page header initialization at the end of archive recovery
* Fix "cannot make new WAL entries during recovery" error

force default values for others
* Ensure that a "fast shutdown" request will forcibly terminate open
sessions, even if a "smart shutdown" was already in progress
* Avoid memory leak for array_agg() in GROUP BY queries
* Treat to_char(..., 'TH') as an uppercase ordinal suffix with 'HH'/'HH12'
monitoring tools and commands. Each user has their own favorite features which
will make day-to-day work with PostgreSQL easier and more productive for them.
Among the most popular enhancements are:
* Parallel Database Restore, speeding up recovery from backup up to 8 times
* Per-Column Permissions, allowing more granular control of sensitive data
* Per-database Collation Support, making PostgreSQL more useful in
multi-lingual environments
* In-place Upgrades through pg_migrator (beta), enabling upgrades from 8.3 to
8.4 without extensive downtime
* New Query Monitoring Tools, giving administrators more insight into query
activity
* Greatly Reduced VACUUM Overhead through the Visibility Map
* New Monitoring Tools for current queries, query load and deadlocks
Version 8.4 also makes data analysis easier through the advanced ANSI SQL2003
features of windowing functions, common table expressions and recursive queries.
Enhancements to stored procedures, such as default parameters and variadic
parameters, make database server programming simpler and more compact.
Of course, there are also performance improvements included in this version.
