Release Notes
+ Release 7.3.9
+
+ Release date: 2005-01-31
+
+ This release contains a variety of fixes from 7.3.8, including several
+ security-related issues.
+ _________________________________________________________________
+
+ Migration to version 7.3.9
+
+ A dump/restore is not required for those running 7.3.X.
+ _________________________________________________________________
+
+ Changes
+
+ * Disallow "LOAD" to non-superusers
+ On platforms that will automatically execute initialization
+ functions of a shared library (this includes at least Windows and
+ ELF-based Unixen), "LOAD" can be used to make the server execute
+ arbitrary code. Thanks to NGS Software for reporting this.
+ * Check that creator of an aggregate function has the right to
+ execute the specified transition functions
+ This oversight made it possible to bypass denial of EXECUTE
+ permission on a function.
+ * Fix security and 64-bit issues in contrib/intagg
+ * Add needed STRICT marking to some contrib functions (Kris Jurka)
+ * Avoid buffer overrun when plpgsql cursor declaration has too many
+ parameters (Neil)
+ * Fix planning error for FULL and RIGHT outer joins
+ The result of the join was mistakenly supposed to be sorted the
+ same as the left input. This could not only deliver mis-sorted
+ output to the user, but in case of nested merge joins could give
+ outright wrong answers.
+ * Fix plperl for quote marks in tuple fields
+ * Fix display of negative intervals in SQL and GERMAN datestyles

Release 7.3.8
Release date: 2004-10-22
in many not-so-corner cases. This would for example allow users to
insert into views they weren't supposed to have permission to
insert into. We have therefore reverted the 7.3.3 patch. The
- original bug will be fixed in 7.5.
+ original bug will be fixed in 8.0.
* Repair incorrect order of operations in GetNewTransactionId()
This bug could result in failure under out-of-disk-space
conditions, including inability to restart even after disk space
This has a variety of fixes from 7.3.4.

Release 7.3
-
+
Release date: 2002-11-27
_________________________________________________________________
-
+
Overview
-
+
Major changes in this release:
-
+
Schemas
Schemas allow users to create objects in separate namespaces,
so two people or applications can have tables with the same
name. There is also a public schema for shared tables.
- Table/index creation can be restricted by removing permissions
+ Table/index creation can be restricted by removing privileges
on the public schema.
-
+
Drop Column
PostgreSQL now supports the ALTER TABLE ... DROP COLUMN
functionality.
-
+
Table Functions
Functions returning multiple rows and/or multiple columns are
now much easier to use than before. You can call such a "table
function" in the SELECT FROM clause, treating its output like a
table. Also, PL/pgSQL functions can now return sets.
-
+
Prepared Queries
PostgreSQL now supports prepared queries, for improved
performance.
-
+
Dependency Tracking
PostgreSQL now records object dependencies, which allows
improvements in many areas. "DROP" statements now take either
CASCADE or RESTRICT to control whether dependent objects are
also dropped.
-
+
Privileges
Functions and procedural languages now have privileges, and
functions can be defined to run with the privileges of their
creator.
-
+
Internationalization
Both multibyte and locale support are now always enabled.
-
+
Logging
A variety of logging options have been enhanced.
-
+
Interfaces
A large number of interfaces have been moved to
http://gborg.postgresql.org where they can be developed and
released independently.
-
+
Functions/Identifiers
By default, functions can now take up to 32 parameters, and
identifiers can be up to 63 bytes long. Also, OPAQUE is now
each of the former meanings of OPAQUE in function argument and
result types.
_________________________________________________________________
-
+
Migration to version 7.3
-
+
A dump/restore using pg_dump is required for those wishing to migrate
data from any previous release. If your application examines the
system catalogs, additional changes will be required due to the
introduction of schemas in 7.3; for more information, see:
- http://www.ca.postgresql.org/docs/momjian/upgrade_tips_7.3.
-
+ http://developer.postgresql.org/~momjian/upgrade_tips_7.3.
+
Observe the following incompatibilities:
-
+
* Pre-6.3 clients are no longer supported.
* "pg_hba.conf" now has a column for the user name and additional
features. Existing files need to be adjusted.
* An empty string ('') is no longer allowed as the input into an
integer field. Formerly, it was silently interpreted as 0.

+ output to the user, but in case of nested merge joins could give
+ outright wrong answers.

Release 7.2
-
+
Release date: 2002-02-04
_________________________________________________________________
-
+
Overview
-
+
This release improves PostgreSQL for use in high-volume applications.
-
+
Major changes in this release:
-
+
VACUUM
Vacuuming no longer locks tables, thus allowing normal user
access during the vacuum. A new "VACUUM FULL" command does
old-style vacuum by locking the table and shrinking the on-disk
copy of the table.
-
+
Transactions
There is no longer a problem with installations that exceed
four billion transactions.
-
+
OIDs
OIDs are now optional. Users can now create tables without OIDs
for cases where OID usage is excessive.
-
+
Optimizer
The system now computes histogram column statistics during
"ANALYZE", allowing much better optimizer choices.
-
+
Security
A new MD5 encryption option allows more secure storage and
transfer of passwords. A new Unix-domain socket authentication
option is available on Linux and BSD systems.
-
+
Statistics
Administrators can use the new table access statistics module
to get fine-grained information about table and index usage.
-
+
Internationalization
Program and library messages can now be displayed in several
languages.
_________________________________________________________________
-
+
Migration to version 7.2
-
+
A dump/restore using "pg_dump" is required for those wishing to
migrate data from any previous release.
-
+
Observe the following incompatibilities:
-
+
* The semantics of the "VACUUM" command have changed in this
release. You may wish to update your maintenance procedures
accordingly.
need to rewrite your applications.
* The timestamp(), time(), and interval() functions are no longer
available. Instead of timestamp(), use timestamp 'string' or CAST.
-
+
The SELECT ... LIMIT #,# syntax will be removed in the next release.
You should change your queries to use separate LIMIT and OFFSET
clauses, e.g. LIMIT 10 OFFSET 20.

Release 7.1
-
+
Release date: 2001-04-13
-
+
This release focuses on removing limitations that have existed in the
PostgreSQL code for many years.
-
+
Major changes in this release:
-
+
Write-ahead Log (WAL)
To maintain database consistency in case of an operating system
crash, previous releases of PostgreSQL have forced all data
performance. If you have been using -F in previous releases to
disable disk flushes, you may want to consider discontinuing
its use.
-
+
TOAST
TOAST - Previous releases had a compiled-in row length limit,
typically 8k - 32k. This limit made storage of long text fields
difficult. With TOAST, long rows of any length can be stored
with good performance.
-
+
Outer Joins
We now support outer joins. The UNION/NOT IN workaround for
outer joins is no longer required. We use the SQL92 outer join
syntax.
-
+
Function Manager
The previous C function manager did not handle null values
properly, nor did it support 64-bit CPU's (Alpha). The new
function manager does. You can continue using your old custom
functions, but you may want to rewrite them in the future to
use the new function manager call interface.
-
+
Complex Queries
A large number of complex queries that were unsupported in
previous releases now work. Many combinations of views,
tables now work properly. Inherited tables are now accessed by
default. Subqueries in FROM are now supported.
_________________________________________________________________
-
+
Migration to version 7.1
-
+
A dump/restore using pg_dump is required for those wishing to migrate
data from any previous release.

Release 7.0
-
+
Release date: 2000-05-08
-
+
This release contains improvements in many areas, demonstrating the
continued growth of PostgreSQL. There are more improvements and fixes
in 7.0 than in any previous release. The developers have confidence
that this is the best release yet; we do our best to put out only
solid releases, and this one is no exception.
-
+
Major changes in this release:
-
+
Foreign Keys
Foreign keys are now implemented, with the exception of PARTIAL
MATCH foreign keys. Many users have been asking for this
feature, and we are pleased to offer it.
-
+
Optimizer Overhaul
Continuing on work started a year ago, the optimizer has been
improved, allowing better query plan selection and faster
performance with less memory usage.
-
+
Updated psql
psql, our interactive terminal monitor, has been updated with a
variety of new features. See the psql manual page for details.
-
+
Join Syntax
SQL92 join syntax is now supported, though only as INNER JOIN

are available, as are column correlation names.

Migration to version 7.0
-
+
A dump/restore using pg_dump is required for those wishing to migrate
data from any previous release of PostgreSQL. For those upgrading from
6.5.*, you may instead use pg_upgrade to upgrade to this release;
however, a full dump/reload installation is always the most robust
method for upgrades.
-
+
Interface and compatibility issues to consider for the new release
include:
-
+
* The date/time types datetime and timespan have been superseded by
the SQL92-defined types timestamp and interval. Although there has
been some effort to ease the transition by allowing PostgreSQL to
in ambiguity with other types implementing LENGTH such as the
geometric types.

Release 6.5
-
+
Release date: 1999-06-09
-
+
This release marks a major step in the development team's mastery of
the source code we inherited from Berkeley. You will see we are now
easily adding major features, thanks to the increasing size and
experience of our world-wide development team.
-
+
Here is a brief summary of the more notable changes:
-
+
Multiversion concurrency control(MVCC)
This removes our old table-level locking, and replaces it with
a locking system that is superior to most commercial database
systems. So, basically, we no longer are restricted by simple
table-level locking; we have something better than row-level
locking.
-
+
Hot backups from pg_dump
pg_dump takes advantage of the new MVCC features to give a
consistent database dump/backup while the database stays online
and available for queries.
-
+
Numeric data type
We now have a true numeric data type, with user-specified
precision.
-
+
Temporary tables
Temporary tables are guaranteed to have unique names within a
database session, and are destroyed on session exit.
-
+
New SQL features
We now have CASE, INTERSECT, and EXCEPT statement support. We
have new LIMIT/OFFSET, SET TRANSACTION ISOLATION LEVEL, SELECT
... FOR UPDATE, and an improved LOCK TABLE command.
-
+
Speedups
We continue to speed up PostgreSQL, thanks to the variety of
talents within our team. We have sped up memory allocation,
optimization, table joins, and row transfer routines.
-
+
Ports
We continue to expand our port list, this time including
Windows NT/ix86 and NetBSD/arm32.
-
+
Interfaces
Most interfaces have new versions, and existing functionality
has been improved.
-
+
Documentation
New and updated material is present throughout the
documentation. New FAQs have been contributed for SGI and AIX
on obtaining the PostgreSQL source tree via anonymous CVS and
CVSup.
_________________________________________________________________
-
+
Migration to version 6.5
-
+
A dump/restore using pg_dump is required for those wishing to migrate
data from any previous release of PostgreSQL. pg_upgrade can *not* be
used to upgrade to this release because the on-disk structure of the
tables has changed compared to previous releases.
-
+
The new Multiversion Concurrency Control (MVCC) features can give
somewhat different behaviors in multiuser environments. *Read and
understand the following section to ensure that your existing
applications will give you the behavior you need.*
_________________________________________________________________
-
+
Multiversion Concurrency Control
Because readers in 6.5 don't lock data, regardless of transaction
sometime after the statement or transaction began) nor that the row is
protected from being deleted or updated by concurrent transactions
before the current transaction does a commit or rollback.
-
+
To ensure the actual existence of a row and protect it against
concurrent updates one must use "SELECT FOR UPDATE" or an appropriate
"LOCK TABLE" statement. This should be taken into account when porting
applications from previous releases of PostgreSQL and other
environments.
-
+
Keep the above in mind if you are using "contrib/refint.*" triggers
for referential integrity. Additional techniques are required now. One
way is to use "LOCK parent_table IN SHARE ROW EXCLUSIVE MODE" command
if a transaction is going to update/delete a primary key and use "LOCK
parent_table IN SHARE MODE" command if a transaction is going to
update/insert a foreign key.
-
+
Note: Note that if you run a transaction in SERIALIZABLE mode then
you must execute the "LOCK" commands above before execution of any
DML statement ("SELECT/INSERT/DELETE/UPDATE/FETCH/COPY_TO") in the
transaction.
-
+
These inconveniences will disappear in the future when the ability to
read dirty (uncommitted) data (regardless of isolation level) and true
referential integrity will be implemented.

Release 6.3
-
+
Release date: 1998-03-01
-
+
There are *many* new features and improvements in this release. Here
is a brief, incomplete summary:
-
+
* Many new SQL features, including full SQL92 subselect capability
(everything is here but target-list subselects).
* Support for client-side environment variables to specify time zone
and date style.
* Socket interface for client/server connection. This is the default
now so you may need to start postmaster with the "-i" flag.
- * Better password authorization mechanisms. Default table
- permissions have changed.
+ * Better password authorization mechanisms. Default table privileges
+ have changed.
* Old-style time travel has been removed. Performance has been
improved.
-
+
Note: Bruce Momjian wrote the following notes to introduce the new
release.
-
+
There are some general 6.3 issues that I want to mention. These are
only the big items that can not be described in one sentence. A review
of the detailed changes list is still needed.
-
+
First, we now have subselects. Now that we have them, I would like to
mention that without subselects, SQL is a very limited language.
Subselects are a major feature, and you should review your code for
may think. Vadim has put us on the big SQL map with subselects, and
fully functional ones too. The only thing you can't do with subselects
is to use them in the target list.
-
+
Second, 6.3 uses Unix domain sockets rather than TCP/IP by default. To
enable connections from other machines, you have to use the new
postmaster -i option, and of course edit "pg_hba.conf". Also, for this
reason, the format of "pg_hba.conf" has changed.
-
+
Third, char() fields will now allow faster access than varchar() or
text. Specifically, the text and varchar() have a penalty for access
to any columns after the first column of this type. char() used to
that you redesign some of your tables, especially if you have short
character columns that you have defined as varchar() or text. This and
other changes make 6.3 even faster than earlier releases.
-
+
We now have passwords definable independent of any Unix file. There
are new SQL USER commands. See the Administrator's Guide for more
information. There is a new table, pg_shadow, which is used to store
SELECT-able by the postgres super-user. pg_user is now a view of
pg_shadow, and is SELECT-able by PUBLIC. You should keep using pg_user
in your application without changes.
-
- User-created tables now no longer have SELECT permission to PUBLIC by
+
+ User-created tables now no longer have SELECT privilege to PUBLIC by
default. This was done because the ANSI standard requires it. You can
- of course GRANT any permissions you want after the table is created.
+ of course GRANT any privileges you want after the table is created.
System tables continue to be SELECT-able by PUBLIC.
-
+
We also have real deadlock detection code. No more sixty-second
timeouts. And the new locking code implements a FIFO better, so there
should be less resource starvation during heavy use.
-
+
Many complaints have been made about inadequate documentation in
previous releases. Thomas has put much effort into many new manuals
for this release. Check out the doc/ directory.
-
+
For performance reasons, time travel is gone, but can be implemented
using triggers (see "pgsql/contrib/spi/README"). Please check out the
new \d command for types, operators, etc. Also, views have their own
- permissions now, not based on the underlying tables, so permissions on
+ privileges now, not based on the underlying tables, so privileges on
them have to be set separately. Check "/pgsql/interfaces" for some new
ways to talk to PostgreSQL.
-
+
This is the first release that really required an explanation for
existing users. In many ways, this was necessary because the new
release removes many limitations, and the work-arounds people were
using are no longer needed.

Release 6.2.1
-
+
Release date: 1997-10-17
-
+
6.2.1 is a bug-fix and usability release on 6.2.
-
+
Summary:
-
+
* Allow strings to span lines, per SQL92.
* Include example trigger function for inserting user names on table
updates.
-
+
This is a minor bug-fix release on 6.2. For upgrades from pre-6.2
systems, a full dump/reload is required. Refer to the 6.2 release
notes for instructions.

Migration from version 6.2 to version 6.2.1
-
+
This is a minor bug-fix release. A dump/reload is not required from
version 6.2, but is required from any release prior to 6.2.
-
+
In upgrading from version 6.2, if you choose to dump/reload you will
find that avg(money) is now calculated correctly. All other bug fixes
take effect upon updating the executables.
-
+
Another way to avoid dump/reload is to use the following SQL command
from "psql" to update the existing system table:
update pg_aggregate set aggfinalfn = 'cash_div_flt8'
This will need to be done to every existing database, including
template1.

-
+
A dump/restore is required for those wishing to migrate data from
previous releases of PostgreSQL.
_________________________________________________________________
-
+
Migration from version 6.1 to version 6.2
-
+
This migration requires a complete dump of the 6.1 database and a
restore of the database in 6.2.
-
+
Note that the "pg_dump" and "pg_dumpall" utility from 6.2 should be
used to dump the 6.1 database.
_________________________________________________________________
-
+
Migration from version 1.x to version 6.2
-
+
Those migrating from earlier 1.* releases should first upgrade to 1.09
because the COPY output format was improved from the 1.02 release.

Release 6.1.1
-
+
Release date: 1997-07-22
_________________________________________________________________
-
+
Migration from version 6.1 to version 6.1.1
-
+
This is a minor bug-fix release. A dump/reload is not required from
version 6.1, but is required from any release prior to 6.1. Refer to
the release notes for 6.1 for more details.
_________________________________________________________________
-

Changes
-
+
fix for SET with options (Thomas)
allow pg_dump/pg_dumpall to preserve ownership of all tables/objects(Bruce)
new psql \connect option allows changing usernames without changing databases
pg_dumpall now returns proper status, portability fix(Bruce)
_________________________________________________________________
-
+
Release 6.1
-
+
Release date: 1997-06-08
-
+
The regression tests have been adapted and extensively modified for
the 6.1 release of PostgreSQL.
-
+
Three new data types (datetime, timespan, and circle) have been added
to the native set of PostgreSQL types. Points, boxes, paths, and
polygons have had their output formats made consistent across the data
types. The polygon output in misc.out has only been spot-checked for
correctness relative to the original regression output.
-
+
PostgreSQL 6.1 introduces a new, alternate optimizer which uses
genetic algorithms. These algorithms introduce a random behavior in
the ordering of query results when the query contains multiple
inherently unordered (e.g. points and time intervals) and tests
involving those types are explicitly bracketed with "set geqo to
'off'" and "reset geqo".
-
+
The interpretation of array specifiers (the curly braces around atomic
values) appears to have changed sometime after the original regression
tests were generated. The current "./expected/*.out" files reflect
this new interpretation, which may not be correct!
-
+
The float8 regression test fails on at least some platforms. This is
due to differences in implementations of pow() and exp() and the
signaling mechanisms used for overflow and underflow conditions.
-
+
The "random" results in the random test should cause the "random" test
to be "failed", since the regression tests are evaluated using a
simple diff. However, "random" does not seem to produce random results
on my test machine (Linux/gcc/i686).
_________________________________________________________________
-
+
Migration to version 6.1
-
+
This migration requires a complete dump of the 6.0 database and a
restore of the database in 6.1.
-
+
Those migrating from earlier 1.* releases should first upgrade to 1.09
because the COPY output format was improved from the 1.02 release.

Release date: 1996-11-04
-
+
Sorry, we didn't keep track of changes from 1.02 to 1.09. Some of the
changes listed in 6.0 were actually included in the 1.02.1 to 1.09
releases.

Release date: 1996-08-01
_________________________________________________________________
-
+
Migration from version 1.02 to version 1.02.1
-
+
Here is a new migration file for 1.02.1. It includes the 'copy' change
and a script to convert old ASCII files.
-
+
Note: The following notes are for the benefit of users who want to
migrate databases from Postgres95 1.01 and 1.02 to Postgres95
1.02.1.
-
+
If you are starting afresh with Postgres95 1.02.1 and do not need
to migrate old databases, you do not need to read any further.
-
+
In order to upgrade older Postgres95 version 1.01 or 1.02 databases to
version 1.02.1, the following steps are required:
1. Start up a new 1.02.1 postmaster
the last two statements in the file because they are already
present in 1.02. This is not a cause for concern.
_________________________________________________________________
-
+
Dump/Reload Procedure
-
+
If you are trying to reload a pg_dump or text-mode, copy tablename to
stdout generated with a previous version, you will need to run the
attached "sed" script on the ASCII file before loading it into the
create operator !~* (leftarg = varchar, rightarg = text, procedure = texticrege
xne);
_________________________________________________________________

databases from Postgres95 1.0 to Postgres95 1.01.
-
+
If you are starting afresh with Postgres95 1.01 and do not need to
migrate old databases, you do not need to read any further.
-
+
In order to Postgres95 version 1.01 with databases created with
Postgres95 version 1.0, the following steps are required:
1. Set the definition of NAMEDATALEN in "src/Makefile.global" to 16
create operator !~* (leftarg = text, rightarg = text, procedure = texticregexne
);

Incompatible changes:
* BETA-0.3 IS INCOMPATIBLE WITH DATABASES CREATED WITH PREVIOUS VERSIONS
(due to system catalog changes and indexing structure changes).
(Also, aggregates can now be overloaded, i.e. you can define your
own MAX aggregate to take in a user-defined type.)
* CHANGE ACL removed. GRANT/REVOKE syntax added.
- - Privileges can be given to a group using the "GROUP" keyword.

+ The key word 'PUBLIC' is also supported to mean all users.
Privileges can only be granted or revoked to one user or group
at a time.
* the bug where aggregates of empty tables were not run has been fixed. Now,
aggregates run on empty tables will return the initial conditions of the
aggregates. Thus, COUNT of an empty table will now properly return 0.
- MAX/MIN of an empty table will return a tuple of value NULL.
+ MAX/MIN of an empty table will return a row of value NULL.
* allow the use of \; inside the monitor
* the LISTEN/NOTIFY asynchronous notification mechanism now work

and then execute the following commands (cut and paste from here):
* added PQdisplayTuples() to libpq and changed monitor and psql to use it
* added NeXT port (requires SysVIPC implementation)
* added CAST .. AS ... syntax
- * added ASC and DESC keywords
+ * added ASC and DESC key words
* added 'internal' as a possible language for CREATE FUNCTION
internal functions are C functions which have been statically linked
into the postgres backend.
Incompatibilities:
* date formats have to be MM-DD-YYYY (or DD-MM-YYYY if you're using
EUROPEAN STYLE). This follows SQL-92 specs.

Enhancements:
* sql LIKE syntax has been added

* fixed non-portable datetimes implementation
* added kerberos flags to the src/backend/Makefile

char(N) and varchar(N) are implemented as truncated text types. In
addition, char(N) does blank-padding.

own MAX aggregate to take in a user-defined type.)
* CHANGE ACL removed. GRANT/REVOKE syntax added.

Bug fixes:
* the bug where aggregates of empty tables were not run has been fixed. Now,
aggregates run on empty tables will return the initial conditions of the

a class is not found. This dissuades non-privileged users from
guessing the existence of privileged classes.
