Обсуждение: FOR IMMEDIATE RELEASE: PostgreSQL v7.1 Release Announcement

Date: Saturday, April 14, 2001
Subject: PostgreSQL v7.1 Release Announcement

The PostgreSQL Global Development Group is pleased to announce
the release of PostgreSQL v7.1, now available for download from
http://www.postgresql.org and our mirror sites.

After a long and arduous development cycle, v7.1 adds several
improvements to the award winning [Linux World 1999, Linux
Journal 2000] PostgreSQL open source Object-based Relational
Database application.

As with all past releases, PostgreSQL v7.1 is the result of
collaberative and cooperative efforts of a worldwide network of
independent developers and companies committed to advancing
PostgreSQL as the best open source database solution. The Global
Development Group wants to thank the hundreds of individual
contributors who have added, tested, and improved PostgreSQL
throughout the development lifecycle of this release.

Key New Features and Capabilities of Version 7.1 Include:

Write-ahead Log (WAL) increases data integrity and processing speed.
         To maintain database consistency in case of an operating
     system crash, previous releases of PostgreSQL have forced all
     all data modifications to disk before each transaction commit.
     With WAL, only one log file must be flushed to disk, greatly
     improving performance.
     (Tech note: can eliminate use of -F in to disable disk flushes)

TOAST (The Oversized-Attribute Storage Technique)
          Past releases had compiled-in row length limit typically
     between 8Kb & 32Kb.  This restriction made storage of long text
     fields difficult, cumbersome and slow. TOAST enables rows of
     any length while maintaing the high performance PostgreSQL
     users have come to expect.

SQL92 Outer Joins are now supported.
     (Tech note: eliminates the UNION/NOT IN workaround)

64-bit C Language Function Manager support
           The previous C function manager did not handle support
     64-bit CPU's (e.g. Alpha, Sun, Itanium).
     (Tech note: This change should not impact existing custom
      functions developed for past versions, but performance will
      be improved through rewriting to use the new call interface.)

Complex Queries that are better, stronger and faster
           Many complex queries were unsupported in previous
     releases. With v7.1 combinations of views, aggregates, UNION,
     LIMIT, cursors, subqueries, and inherited tables are enabled.
     Inherited tables are now accessed by default, and subqueries
     in FROM are now supported.

As good a place to put it as any, I guess. After a long sojourn
with MySQL I needed to go back to PostgreSQL. Installed v7.0 but
was waiting patiently for v7.1.

Then on the port.

Then I was ready to activate it. Alas, it was not to be. For
some reason I can't "initdb -W -D /home/db/...". Or rather,
I can get my cake but not in any eadible condition so to
speak. Which is no good.

I want to eat my cake!

I can't even create a database cluster, nay, system in its
default place. Well, not in any ...

The v7.0 release on the production box has no such troubles. I
can get and eat all the cake I want, as long as it's v7.0 cake.

Haven't yet tried to see v7.0 databases are v7.1 compatible.

Since I've unsubscribed the pgsql maillists some years ago, does
anyone here know if this is 'known'? Or if it's me in which case
the details of the errors of my ways would be very much appreciated!
