postgresql-8.4 8.4.9-1 source package in Ubuntu
Changelog
postgresql-8.4 (8.4.9-1) unstable; urgency=low * New upstream bug fix release: - Fix bugs in indexing of in-doubt HOT-updated tuples. These bugs could result in index corruption after reindexing a system catalog. They are not believed to affect user indexes. - Fix multiple bugs in GiST index page split processing. The probability of occurrence was low, but these could lead to index corruption. - Fix possible buffer overrun in tsvector_concat(). The function could underestimate the amount of memory needed for its result, leading to server crashes. - Fix crash in xml_recv when processing a "standalone" parameter. - Make pg_options_to_table return NULL for an option with no value. Previously such cases would result in a server crash. - Avoid possibly accessing off the end of memory in "ANALYZE" and in SJIS-2004 encoding conversion. This fixes some very-low-probability server crash scenarios. - Prevent intermittent hang in interactions of startup process with bgwriter process. This affected recovery in non-hot-standby cases. - Fix race condition in relcache init file invalidation. There was a window wherein a new backend process could read a stale init file but miss the inval messages that would tell it the data is stale. The result would be bizarre failures in catalog accesses, typically "could not read block 0 in file ..." later during startup. - Fix memory leak at end of a GiST index scan. Commands that perform many separate GiST index scans, such as verification of a new GiST-based exclusion constraint on a table already containing many rows, could transiently require large amounts of memory due to this leak. - Fix incorrect memory accounting (leading to possible memory bloat) in tuplestores supporting holdable cursors and plpgsql's RETURN NEXT command. - Fix performance problem when constructing a large, lossy bitmap. - Fix join selectivity estimation for unique columns. This fixes an erroneous planner heuristic that could lead to poor estimates of the result size of a join. - Fix nested PlaceHolderVar expressions that appear only in sub-select target lists. This mistake could result in outputs of an outer join incorrectly appearing as NULL. - Allow nested EXISTS queries to be optimized properly. - Fix array- and path-creating functions to ensure padding bytes are zeroes. This avoids some situations where the planner will think that semantically-equal constants are not equal, resulting in poor optimization. - Fix "EXPLAIN" to handle gating Result nodes within inner-indexscan subplans. The usual symptom of this oversight was "bogus varno" errors. - Work around gcc 4.6.0 bug that breaks WAL replay. This could lead to loss of committed transactions after a server crash. - Fix dump bug for VALUES in a view. - Disallow SELECT FOR UPDATE/SHARE on sequences. This operation doesn't work as expected and can lead to failures. - Fix "VACUUM" so that it always updates pg_class.reltuples/relpages. This fixes some scenarios where autovacuum could make increasingly poor decisions about when to vacuum tables. - Defend against integer overflow when computing size of a hash table. - Fix cases where "CLUSTER" might attempt to access already-removed TOAST data. - Fix portability bugs in use of credentials control messages for "peer" authentication. - Fix SSPI login when multiple roundtrips are required. The typical symptom of this problem was "The function requested is not supported" errors during SSPI login. - Throw an error if "pg_hba.conf" contains hostssl but SSL is disabled. This was concluded to be more user-friendly than the previous behavior of silently ignoring such lines. - Fix typo in pg_srand48 seed initialization. This led to failure to use all bits of the provided seed. This function is not used on most platforms (only those without srandom), and the potential security exposure from a less-random-than-expected seed seems minimal in any case. - Avoid integer overflow when the sum of LIMIT and OFFSET values exceeds 2^63. - Add overflow checks to int4 and int8 versions of generate_series(). - Fix trailing-zero removal in to_char(). In a format with FM and no digit positions after the decimal point, zeroes to the left of the decimal point could be removed incorrectly. - Fix pg_size_pretty() to avoid overflow for inputs close to 2^63. - Weaken plpgsql's check for typmod matching in record values. An overly enthusiastic check could lead to discarding length modifiers that should have been kept. - Fix pg_upgrade to preserve toast tables' relfrozenxids during an upgrade from 8.3. Failure to do this could lead to "pg_clog" files being removed too soon after the upgrade. - Fix psql's counting of script file line numbers during COPY from a different file. - Fix pg_restore's direct-to-database mode for standard_conforming_strings. pg_restore could emit incorrect commands when restoring directly to a database server from an archive file that had been made with standard_conforming_strings set to on. - Be more user-friendly about unsupported cases for parallel pg_restore. This change ensures that such cases are detected and reported before any restore actions have been taken. - Fix write-past-buffer-end and memory leak in libpq's LDAP service lookup code. - In libpq, avoid failures when using nonblocking I/O and an SSL connection. - Improve libpq's handling of failures during connection startup. In particular, the response to a server report of fork() failure during SSL connection startup is now saner. - Improve libpq's error reporting for SSL failures. - Fix PQsetvalue() to avoid possible crash when adding a new tuple to a PGresult originally obtained from a server query. - Make ecpglib write double values with 15 digits precision. - In ecpglib, be sure LC_NUMERIC setting is restored after an error. - Apply upstream fix for blowfish signed-character bug (CVE-2011-2483) (Closes: #631285) "contrib/pg_crypto"'s blowfish encryption code could give wrong results on platforms where char is signed (which is most), leading to encrypted passwords being weaker than they should be. - Fix memory leak in "contrib/seg". - Fix pgstatindex() to give consistent results for empty indexes. - Allow building with perl 5.14. (Closes: #628503) * Drop 16-cmsgcred-size.patch, fixed upstream in a different way. -- Ubuntu Archive Auto-Sync <email address hidden> Mon, 17 Oct 2011 13:46:23 +0000

Binary packages built by this source
- postgresql-8.4: object-relational SQL database, version 8.4 server
PostgreSQL is a fully featured object-relational database management
system. It supports a large part of the SQL standard and is designed
to be extensible by users in many aspects. Some of the features are:
ACID transactions, foreign keys, views, sequences, subqueries,
triggers, user-defined types and functions, outer joins, multiversion
concurrency control. Graphical user interfaces and bindings for many
programming languages are available as well.
.
This package provides the database server for PostgreSQL 8.4. Servers
for other major release versions can be installed simultaneously and
are coordinated by the postgresql-common package. A package providing
ident-server is needed if you want to authenticate remote connections
with identd.
- postgresql-client-8.4: front-end programs for PostgreSQL 8.4
This package contains client and administrative programs for
PostgreSQL: these are the interactive terminal client psql and
programs for creating and removing users and databases.
.
This is the client package for PostgreSQL 8.4. If you install
PostgreSQL 8.4 on a standalone machine, you need the server package
postgresql-8.4, too. On a network, you can install this package on
many client machines, while the server package may be installed on
only one machine.

- postgresql-contrib-8.4: additional facilities for PostgreSQL
The PostgreSQL contrib package provides several additional features
for the PostgreSQL database. This version is built to work with the
server package postgresql-8.4. contrib often serves as a testbed for
features before they are adopted into PostgreSQL proper:
.
adminpack - File and log manipulation routines, used by pgAdmin
btree_gist - B-Tree indexing using GiST (Generalised Search Tree)
chkpass - An auto-encrypted password datatype
cube - Multidimensional-cube datatype (GiST indexing example)
dblink - Functions to return results from a remote database
earthdistance - Operator for computing the distance (in miles) between
two points on the earth's surface
fuzzystrmatch - Levenshtein, metaphone, and soundex fuzzy string matching
hstore - Store (key, value) pairs
intagg - Integer aggregator/enumerator
_int - Index support for arrays of int4, using GiST (benchmark
needs the libdbd-pg-perl package)
isn - type extensions for ISBN, ISSN, ISMN, EAN13 product numbers
lo - Large Object maintenance
ltree - Tree-like data structures
oid2name - Maps OIDs to table names
pageinspect - Inspection of database pages
pg_buffercache - Real time queries on the shared buffer cache
pg_freespacemap- Displays the contents of the free space map (FSM)
pg_trgm - Determine the similarity of text based on trigram matching
pg_standby - Create a warm stand-by server
pgbench - TPC-B like benchmark
pgcrypto - Cryptographic functions
pgrowlocks - A function to return row locking information
pgstattuple - Returns the percentage of dead tuples in a table; this
indicates whether a vacuum is required.
seg - Confidence-interval datatype (GiST indexing example)
spi - PostgreSQL Server Programming Interface; 4 examples of
its use:
autoinc - A function for implementing AUTOINCREMENT/
IDENTITY
insert_ username - function for inserting user names
moddatetim e - Update modification timestamps
refint - Functions for implementing referential
integrity (foreign keys). Note that this is
now superseded by built-in referential
integrity.
timetravel - Re-implements in user code the time travel
feature that was removed in 6.3.
tablefunc - examples of functions returning tables
uuid-ossp - UUID generation functions
vacuumlo - Remove orphaned large objects
