Log message:
Bump the PKGREVISION for all packages which depend directly on perl,
to trigger/signal a rebuild for the transition 5.10.1 -> 5.12.1.

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.

sno@ was right after all, obache@ kindly asked and he@ led the
way. Thanks!

Log message:
Changes 8.4.4:
* Enforce restrictions in plperl using an opmask applied to the whole
  interpreter, instead of using "Safe.pm"
* Prevent PL/Tcl from executing untrustworthy code from pltcl_modules
* Fix data corruption during WAL replay of ALTER ... SET TABLESPACE
* Fix possible crash if a cache reset message is received during
  rebuild of a relcache entry
* Apply per-function GUC settings while running the language
  validator for the function
* Do constraint exclusion for inherited "UPDATE" and \ 
"DELETE" target
  tables when constraint_exclusion = partition
* Do not allow an unprivileged user to reset superuser-only parameter
  settings
* Avoid possible crash during backend shutdown if shutdown occurs
  when a CONTEXT addition would be made to log entries
* Fix erroneous handling of %r parameter in recovery_end_command
* Ensure the archiver process responds to changes in archive_command
  as soon as possible
* Fix pl/pgsql's CASE statement to not fail when the case expression
  is a query that returns no rows
* Update pl/perl's "ppport.h" for modern Perl versions
* Fix assorted memory leaks in pl/python
* Handle empty-string connect parameters properly in ecpg
* Prevent infinite recursion in psql when expanding a variable that
  refers to itself
* Fix psql's \copy to not add spaces around a dot within \copy
  (select ...)
* Avoid formatting failure in psql when running in a locale context
  that doesn't match the client_encoding
* Fix unnecessary "GIN indexes do not support whole-index scans"
  errors for unsatisfiable queries using "contrib/intarray" operators
* Ensure that "contrib/pgstattuple" functions respond to cancel
  interrupts promptly
* Make server startup deal properly with the case that shmget()
  returns EINVAL for an existing shared memory segment
* Avoid possible crashes in syslogger process on Windows
* Deal more robustly with incomplete time zone information in the
  Windows registry
* Update the set of known Windows time zone names
* Update time zone data files to tzdata release 2010j for DST law

  Morocco, Pakistan, Palestine, Russia, Syria, Tunisia; also
  historical corrections for Taiwan.
  Also, add PKST (Pakistan Summer Time) to the default set of
  timezone abbreviations.

Log message:
Changes 8.4.3:
* Add new configuration parameter ssl_renegotiation_limit to control
  how often we do session key renegotiation for an SSL connection
* Fix possible deadlock during backend startup
* Fix possible crashes due to not handling errors during relcache
  reload cleanly
* Fix possible crash due to use of dangling pointer to a cached plan
* Fix possible crash due to overenthusiastic invalidation of cached
  plan for "ROLLBACK"
* Fix possible crashes when trying to recover from a failure in
  subtransaction start
* Fix server memory leak associated with use of savepoints and a
  client encoding different from server's encoding
* Fix incorrect WAL data emitted during end-of-recovery cleanup of a
  GIST index page split
* Fix bug in WAL redo cleanup method for GIN indexes
* Fix incorrect comparison of scan key in GIN index search
* Make substring() for bit types treat any negative length as meaning
  "all the rest of the string"
  The previous coding treated only -1 that way, and would produce an
  invalid result value for other negative values, possibly leading to
  a crash (CVE-2010-0442).
* Fix integer-to-bit-string conversions to handle the first
  fractional byte correctly when the output bit width is wider than
  the given integer by something other than a multiple of 8 bits
* Fix some cases of pathologically slow regular expression matching
* Fix bug occurring when trying to inline a SQL function that returns
  a set of a composite type that contains dropped columns
* Fix bug with trying to update a field of an element of a
  composite-type array column
* Avoid failure when "EXPLAIN" has to print a FieldStore or
  assignment ArrayRef expression
  These cases can arise now that "EXPLAIN VERBOSE" tries to print
  plan node target lists.
* Avoid an unnecessary coercion failure in some cases where an
  undecorated literal string appears in a subquery within
  "UNION"/"INTERSECT"/"EXCEPT"
  This fixes a regression for some cases that worked before 8.4.
* Avoid undesirable rowtype compatibility check failures in some
  cases where a whole-row Var has a rowtype that contains dropped
  columns
* Fix the STOP WAL LOCATION entry in backup history files to report
  the next WAL segment's name when the end location is exactly at a
  segment boundary
* Always pass the catalog ID to an option validator function
  specified in "CREATE FOREIGN DATA WRAPPER"
* Fix some more cases of temporary-file leakage
* Add support for doing FULL JOIN ON FALSE
* Improve constraint exclusion processing of boolean-variable cases,
  in particular make it possible to exclude a partition that has a
  "bool_column = false" constraint
* Prevent treating an INOUT cast as representing binary compatibility
* Include column name in the message when warning about inability to
  grant or revoke column-level privileges
  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.
* Disallow GSSAPI authentication on local connections, since it
  requires a hostname to function correctly
* Protect ecpg against applications freeing strings unexpectedly
* Make ecpg report the proper SQLSTATE if the connection disappears
* Fix translation of cell contents in psql \d output
* Fix psql's numericlocale option to not format strings it shouldn't
  in latex and troff output formats
* Fix a small per-query memory leak in psql
* Make psql return the correct exit status (3) when ON_ERROR_STOP and
  --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 plpgsql failure in one case where a composite column is set to NULL
* Fix possible failure when calling PL/Perl functions from PL/PerlU
  or vice versa
* Add volatile markings in PL/Python to avoid possible
  compiler-specific misbehavior
* Ensure PL/Tcl initializes the Tcl interpreter fully
  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.

  an outer join
* Fix Windows shared-memory allocation code
* Fix locale handling with plperl

  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'

Log message:
Many of the changes in PostgreSQL 8.4 are new or improved administration and
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.
