* 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

* Ensure that a snapshot is available to datatype input functions
* Make it safer for SPI-using functions to be used within datatype

* 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

reading its whole result

and historical DST corrections in Switzerland, Cuba)

* 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)

Bug-fix release, see HISTORY for details.

* Make pg_get_ruledef() parenthesize negative constants (Tom)
Before this fix, a negative constant in a view or rule might be
dumped as, say, -42::integer, which is subtly incorrect: it should
be (-42)::integer due to operator precedence rules. Usually this
would make little difference, but it could interact with another
recent patch to cause PostgreSQL to reject what had been a valid
"SELECT DISTINCT" view query. Since this could result in pg_dump
output failing to reload, it is being treated as a high-priority
fix. The only released versions in which dump output is actually
incorrect are 8.3.1 and 8.2.7.
* Make "ALTER AGGREGATE ... OWNER TO" update pg_shdepend (Tom)
This oversight could lead to problems if the aggregate was later
involved in a "DROP OWNED" or "REASSIGN OWNED" operation.

This release contains a variety of fixes from 8.2.5, including fixes
for significant security issues.

then automatically generate a PLIST that says "${PKGNAME} has no files".
* If PLIST_SRC and GENERATE_PLIST are not set in a package Makefile,
and no PLIST files exist, then fail during the package build with
PKG_FAIL_REASON.
* Remove "intentionally empty" PLISTs again.
Now, the easy way to say that a package installs no files is to just
add the following to the package Makefile:
PLIST_SRC= # empty

that directly manipulate empty PLISTs.
Modify plist/plist.mk so that if the PLIST files are missing and no
GENERATE_PLIST is defined, then the package fails to build.
