with postgresql as a meta-package. Major changes from version 7.1.1
include:
Write-ahead Log (WAL) - To maintain database consistency in
case of an operating system crash, previous releases of PostgreSQL
have forced all data modifications to disk before each transaction
commit. With WAL, only one log file must be flushed to disk, greatly
improving performance. If you have been using -F in previous releases
to disable disk flushes, you may want to consider discontinuing its
use.
TOAST - Previous releases had a compiled-in row length limit,
typically 8 - 32 kB. 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 NULLs 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, aggregates, UNION, LIMIT, cursors, subqueries, and inherited
tables now work properly. Inherited tables are now accessed by
default. Subqueries in FROM are now supported.
Migration to 7.1.1
A dump/restore using pg_dump is required for those wishing to migrate
data from any previous release.

A HUGE number of bug/performance fixes and minor enhancements.
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
overhauled, allowing improved query execution and better
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.
Upcoming Features
In 7.1 or 7.2, we plan to have outer joins, storage for very
long rows, and a write-ahead logging system.
A dump/restore using pg_dump is required for those wishing to migrate
data from any previous release. For those upgrading from 6.5.*, you
can use pg_upgrade to upgrade to this release.

${PREFIX}/${PGSQL_USER} to match hier(7) expectations. The Tcl and Tk
interfaces are now split out into separate packages.

All this may eventually be replaced if the client stuff is factored out of the
postgresql package, but that's not me.

removed, but this should still function correctly on a.out systems. This
package was originally submitted by D'Arcy J.M. Cain, but with major
overhauling by me.
Closes PR#7865 and relevant part of PR#8299.
Major changes from version 6.4.2:
Multi-version 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. In a traditional system, each row that is modified is
locked until committed, preventing reads by other users. MVCC
uses the natural multi-version nature of PostgreSQL to allow
readers to continue reading consistent data during writer
activity. Writers continue to use the compact pg_log transaction
system. This is all performed without having to allocate a lock
for every row like traditional 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
consistant 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
WinNT/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
platforms. The Tutorial has introductory information on SQL from
Stefan Simkovics. For the User's Guide, there are reference pages
covering the postmaster and more utility programs, and a new
appendix contains details on date/time behavior. The
Administrator's Guide has a new chapter on troubleshooting from
Tom Lane. And the Programmer's Guide has a description of query
processing, also from Stefan, and details on obtaining the
Postgres source tree via anonymous CVS and CVSup.
