Fixed meta package building

Log message:
Changes 8.2.16:
* 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

  client encoding different from server's encoding
* Fix incorrect WAL data emitted during end-of-recovery cleanup of a
  GIST index page split
* 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).

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

* 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

* Improve constraint exclusion processing of boolean-variable cases,
  in particular make it possible to exclude a partition that has a
  "bool_column = false" constraint
* 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.
* Fix psql's numericlocale option to not format strings it shouldn't
  in latex and troff output formats
* 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 possible failure when calling PL/Perl functions from PL/PerlU
  or vice versa
* Add volatile markings in PL/Python to avoid possible

  specified to a dblink_build_sql_* function
* Fix assorted crashes in "contrib/xml2" caused by sloppy memory
  management

  the end of checkpoint

* Fix money data type to work in locales where currency amounts have
  no fractional digits, e.g. Japan
* Properly round datetime input like 00:12:57.9999999999999999999999999999
* Fix poor choice of page split point in GiST R-tree operator classes
* Avoid performance degradation in bulk inserts into GIN indexes when
  the input values are (nearly) in sorted order

Log message:
Changes 8.2.13:
* Prevent error recursion crashes when encoding conversion fails.
* Disallow "CREATE CONVERSION" with the wrong encodings for the
  specified conversion function.
* Fix core dump when to_char() is given format codes that are
  inappropriate for the type of the data argument.
* Fix possible failure in "contrib/tsearch2" when C locale is used
  with a multi-byte encoding.
* Fix extreme inefficiency in "contrib/tsearch2" parser's handling of
  an email-like string containing multiple @ characters.
* Fix decompilation of CASE WHEN with an implicit coercion.
* Fix possible misassignment of the owner of a TOAST table's rowtype.
* Fix PL/pgSQL to not treat INTO after "INSERT" as an INTO-variables
  clause anywhere in the string, not only at the start; in
  particular, don't fail for "INSERT INTO" within "CREATE RULE".
* Clean up PL/pgSQL error status variables fully at block exit.
* Retry failed calls to CallNamedPipe() on Windows.
* Add MUST (Mauritius Island Summer Time) to the default list of
  known timezone abbreviations.

Log message:
Changes 8.2.12:
* Improve handling of URLs in headline() function
* Improve handling of overlength headlines in headline() function
* Prevent possible Assert failure or misconversion if an encoding
  conversion is created with the wrong conversion function for the
  specified pair of encodings
* Fix possible Assert failure if a statement executed in PL/pgSQL is
  rewritten into another kind of statement, for example if an
  "INSERT" is rewritten into an "UPDATE"
* Ensure that a snapshot is available to datatype input functions
* Make it safer for SPI-using functions to be used within datatype
  I/O; in particular, to be used in domain check constraints
* Avoid unnecessary locking of small tables in "VACUUM"
* Fix a problem that made UPDATE RETURNING tableoid return zero
  instead of the correct OID
* Fix planner misestimation of selectivity when transitive equality
  is applied to an outer-join clause
  This could result in bad plans for queries like ... from a left
  join b on a.a1 = b.b1 where a.a1 = 42 ...
* Improve optimizer's handling of long IN lists
  This change avoids wasting large amounts of time on such lists when
  constraint exclusion is enabled.
* Ensure that the contents of a holdable cursor don't depend on the
  contents of TOAST tables
* Fix memory leak when a set-returning function is terminated without
  reading its whole result

* Fix possible garbage output from "contrib/sslinfo" functions
* Fix configure script to properly report failure when unable to
  obtain linkage information for PL/Perl

  appropriate, instead of the now-decommissioned pgsql-ports and
  pgsql-patches mailing lists
* Update time zone data files to tzdata release 2009a (for Kathmandu
  and historical DST corrections in Switzerland, Cuba)

Log message:
Changes 8.2.11:
* Fix GiST index corruption due to marking the wrong index entry
  "dead" after a deletion.
  This would result in index searches failing to find rows they
  should have found.
* Fix backend crash when the client encoding cannot represent a
  localized error message.
  We have addressed similar issues before, but it would still fail if
  the "character has no equivalent" message itself couldn't be
  converted. The fix is to disable localization and send the plain
  ASCII error message when we detect such a situation.
* Fix possible crash when deeply nested functions are invoked from a
  trigger.
* Improve optimization of "expression" IN \ 
("expression-list") queries.
  Cases in which there are query variables on the right-hand side had
  been handled less efficiently in 8.2.x and 8.3.x than in prior
  versions. The fix restores 8.1 behavior for such cases.
* Fix mis-expansion of rule queries when a sub-SELECT appears in a
  function call in FROM, a multi-row VALUES list, or a RETURNING list.
* Fix memory leak during rescan of a hashed aggregation plan.
* Ensure an error is reported when a newly-defined PL/pgSQL trigger
  function is invoked as a normal function.
* Prevent possible collision of relfilenode numbers when moving a
  table to another tablespace with "ALTER SET TABLESPACE".
  The command tried to re-use the existing filename, instead of
  picking one that is known unused in the destination directory.
* Fix incorrect tsearch2 headline generation when single query item
  matches first word of text.
* Fix improper display of fractional seconds in interval values when
  using a non-ISO datestyle in an "--enable-integer-datetimes" build.
* Ensure SPI_getvalue and SPI_getbinval behave correctly when the
  passed tuple and tuple descriptor have different numbers of columns.
* Fix ecpg's parsing of "CREATE ROLE".
* Fix recent breakage of pg_ctl restart.
* Ensure "pg_control" is opened in binary mode.
  pg_controldata and pg_resetxlog did this incorrectly, and so could
  fail on Windows.
* Update time zone data files to tzdata release 2008i (for DST law
  changes in Argentina, Brazil, Mauritius, Syria)
