Release Notes

Release 8.0.2

Release date: 2005-04-07

This release contains a variety of fixes from 8.0.1.

__________________________________________________________________

Migration to version 8.0.2

A dump/restore is not required for those running 8.0.*. This release

updates the major version number of the PostgreSQL libraries, so it

might be necessary to re-link some user applications if they cannot

find the properly-numbered shared library.

__________________________________________________________________

Changes

* Increment the major version number of all interface libraries

(Bruce)

This should have been done in 8.0.0. It is required so 7.4.X

versions of PostgreSQL client applications, like psql, can be used

on the same machine as 8.0.X applications. This might require

re-linking user applications that use these libraries.

* Add Windows-only wal_sync_method setting of "fsync_writethrough"

(Magnus, Bruce)

This setting causes PostgreSQL to write through any disk-drive

write cache when writing to WAL. This behavior was formerly called

"fsync", but was renamed because it acts quite differently from

"fsync" on other platforms.

* Enable the wal_sync_method setting of "open_datasync" on Windows,

and make it the default for that platform (Magnus, Bruce)

Because the default is no longer "fsync_writethrough", data loss is

possible during a power failure if the disk drive has write caching

enabled. To turn off the write cache on Windows, from the Device

Manager, choose the drive properties, then Policies.

* New cache management algorithm 2Q replaces ARC (Tom)

This was done to avoid a pending US patent on ARC. The 2Q code

might be a few percentage points slower than ARC for some work

loads. A better cache management algorithm will appear in 8.1.

* Planner adjustments to improve behavior on freshly-created tables

(Tom)

* Allow plpgsql to assign to an element of an array that is initially

NULL (Tom)

Formerly the array would remain NULL, but now it becomes a

single-element array. The main SQL engine was changed to handle

"UPDATE" of a null array value this way in 8.0, but the similar

case in plpgsql was overlooked.

* Convert \r\n and \r to \n in plpython function bodies (Michael

Fuhr)

This prevents syntax errors when plpython code is written on a

Windows or Mac client.

* Allow SPI cursors to handle utility commands that return rows, such

as "EXPLAIN" (Tom)

* Fix "CLUSTER" failure after "ALTER TABLE SET WITHOUT OIDS" (Tom)

* Reduce memory usage of "ALTER TABLE ADD COLUMN" (Neil)

* Fix "ALTER LANGUAGE RENAME" (Tom)

* Document the Windows-only register and unregister options of pg_ctl

(Magnus)

* Ensure operations done during backend shutdown are counted by

statistics collector

This is expected to resolve reports of pg_autovacuum not vacuuming

the system catalogs often enough -- it was not being told about

catalog deletions caused by temporary table removal during backend

exit.

* Change the Windows default for configuration parameter

log_destination to "eventlog" (Magnus)

By default, a server running on Windows will now send log output to

the Windows event logger rather than standard error.

* Make Kerberos authentication work on Windows (Magnus)

* Allow "ALTER DATABASE RENAME" by superusers who aren't flagged as

having CREATEDB privilege (Tom)

* Modify WAL log entries for "CREATE" and "DROP DATABASE" to not

specify absolute paths (Tom)

This allows point-in-time recovery on a different machine with

possibly different database location. Note that "CREATE TABLESPACE"

still poses a hazard in such situations.

* Fix crash from a backend exiting with an open transaction that

created a table and opened a cursor on it (Tom)

* Fix array_map() so it can call PL functions (Tom)

* Several "contrib/tsearch2" and "contrib/btree_gist" fixes (Teodor)

* Fix crash of some "contrib/pgcrypto" functions on some platforms

(Marko Kreen)

* Fix "contrib/intagg" for 64-bit platforms (Tom)

* Fix ecpg bugs in parsing of "CREATE" statement (Michael)

* Work around gcc bug on powerpc and amd64 causing problems in ecpg

(Christof Petig)

* Do not use locale-aware versions of upper(), lower(), and initcap()

when the locale is C (Bruce)

This allows these functions to work on platforms that generate

errors for non-7-bit data when the locale is C.

* Fix quote_ident() to quote names that match keywords (Tom)

* Fix to_date() to behave reasonably when CC and YY fields are both

used (Karel)

* Prevent to_char(interval) from failing when given a zero-month

interval (Tom)

* Fix wrong week returned by date_trunc('week') (Bruce)

date_trunc('week') returned the wrong year for the first few days

of January in some years.

* Use the correct default mask length for class D addresses in INET

data types (Tom)
