8.1 release notes

From

I have compiled the 8.1 release notes and converted them to SGML at:
 http://candle.pha.pa.us/main/writings/pgsql/sgml/release.html#RELEASE-8-1

I still need to add markup and cleanup, but it is good enough for
review and for beta1.  I will work on it more tomorrow.

I spotted a couple of typos:

I think that 'not' should be 'now' in the following:
In previous releases, the only way to use index for MIN/MAX was to rewrite the query as SELECT col FROM tab ORDER BY
colLIMIT 1. This not happens automatically.
 

I think that 'of' should be 'off' in the following:
To prevent partial disk writes from corrupting the database, PostgreSQL writes a complete copy of each database disk
pageto WAL the first time it is modified after a checkpoint. This turns of that functionality for users with
battery-backeddisk caches where partial page writes can not happen.
 

I don't think you want a double negative ('not' and 'INconsistant') in the
following:
In release 8.0, carriage returns and line feeds in CSV COPY TO were not processed in a inconsitent manner. (This was
documentedon the TODO list.)

JFYI:

"Allow indexes to be used for MIN/MAX (Tom)

In previous releases, the only way to use index for MIN/MAX was to
rewrite the query as SELECT col FROM tab ORDER BY col LIMIT 1. This not
happens automatically."

I guess this should read "This now happens automatically"

I think this is an understatement and does not really say what was done:
Replace pg_shadow and pg_group by new role-capable catalogs pg_authid 
and pg_auth_members.

I would include something like "Implement SQL-compliant ROLE support...".

I believe "Make default_with_oids default to false" and "Change 
add_missing_from to 'false'" should be mentioned in the "Migration" section.
This section should say "Migration to version 8.1" instead of "Migration 
to version 8.0".

"This caused CREATE DATABASE to sometimes fail because a new database 
can not be created if anyone else is in the template database."
Shouldn't this read:
"This caused CREATE DATABASE to sometimes fail because a new database 
could not be created if anyone else was in the template database."

"With this change, the default connection database is now 'postgres', 
meaning is is much less likely someone will be using template1 during 
CREATE DATABASE."
... meaning it is much less likely ...

There are some items that are appended to the last one. E.g. "Fix 
interval division and multiplication (Bruce)"
Other times, the additional comments have their own bullet.

These I don't really understand:
- Improve rtree index capabilities and performance (Neil)
- Replace rtree index code with code from /contrib/rtree_gist (Tom)

So first Neil improved the performance for rtree, then rtree was 
replaced with rtree_gist? So Neil's optimizations are gone?

What file should I send patches against next time? ;-)

iiuc, It's *always* the case that a new database can not be created  
if anyone is connected to template1, so *can not be* is more  
appropriate than *could not be*. It's still the case that if someone  
is connected to template1 when a CREATE DATABASE is issued, the  
command will fail.

Bruce,

I have also noticed a small error:

a.. Remove old *.backup files when we do pg_stop_backup() (Bruce)

a.. This prevents a large number of *.backup files from existing in 
pg_xlog/.

I think there should not be a point on the left of the second line because 
it's the details of the first line.

A couple of (other) items I have been involved with that might deserve a 
mention:

. pl/perl support for strict mode
. improved regression framework, - separate db names for separate suites 
(standard regression, PL, contrib), loadable languages, standardised 
framework for PLs.

(We're still working in strict mode but we'll get it fixed in the next 
few days)

And I am not sure if this counts as a bug fix or a feature :-) :

. pl/perl logging of non-fatal warnings

That was completed after I pulled CVS, I think.  It will be updated

That isn't something we usually mention in the release notes, but I can

Not sure how Bruce got the latter out of this commit message:
Migrate rtree_gist functionality into the core system, and add somebasic regression tests for GiST to the standard
regressiontests. 
 

All that's really happened is that GiST actually has a couple of
opclasses in the core system now, whereas previously they were all
contrib (meaning that GiST was dead weight in a standard installation).

It's also now true that everything you can do with the standard rtree
opclasses, you can do with standard GiST opclasses.

There was some talk of obsoleting rtree further down the road, but it
isn't happening in 8.1.  If no serious bugs crop up in all the new GiST
work Teodor and Oleg did, we might consider obsoleting rtree in 8.2.

Before this patch, any non-fatal perl warning, either generated by perl 
itself of by the user calling the builtin function warn(), was dropped 
in the bit bucket. Now it is logged at NOTICE level.

Is a dump/restore required for upgrading from 8.0.x? It might be nice to
note what features require this (2PC?).

Major releases always require a dump/reload because of regular system
catalog and heap/index changes during development.

Duh, I was equating major version number to requiring pg_dump... it's
just been too long since 7.3->7.4. Sorry. :)

Regarding E.1.3.4 (Object Manipulation Changes):

---------
Allow ALTER OWNER commands to be performed by the object owner as well
as the superuser (Stephen Frost)

Prior releases only allowed super-user to change object owners, even if
the current owner was executing the command and the new owner have
permission to create objects of that type.
---------

This isn't *quite* right and implies an ability some might frown upon
("giving away" objects) that isn't actually allowed by my changes.
How about:

---------
Allow ALTER OWNER commands to be performed by the object owner (Stephen
Frost)

Prior releases only allowed a single user to own an object.  With the
addition of role support (where a role can own an object and that role
can have members) it's now possible for multiple users to have ownership
rights on a given object.  ALTER OWNER has been updated to allow
changing the ownership of an object when the user has ownership rights
on the object, is in the new owner role, and the new owner role has
the right to create the object.
---------

Unfortunately, though there was some discussion on it, it seems that the
new owner role must have rights to create the object even if the user
doing the ALTER OWNER owns the schema/db in question.  This means a user
would have to first grant create privileges to the unpriviledged role,
change the ownership to that role, and then reokve the create privileges.
This also means that a number of explicit 'superuser()' checks were
added after I had worked to minimize them.  I'd still like to see the
explicit superuser() checks removed in favor of checking schema
ownership but I'm guessing it's too late for that now.

Perhaps after 8.1 is released we'll get some conversation regarding
these kinds of things which goes beyond just Tom and I.  I don't mind
discussing it with Tom but it'd be nice to get some fresh viewpoints on
the subject and eventually "I think it's better", "I don't like it" gets
kind of boring and can be difficult to work past (well, except he has
commit access and I don't... ;).
Thanks,

Good description, updated to:
       Allow limited <command>ALTER OWNER</> commands to be performed       by the object owner (Stephen Frost)
       Prior releases allowed only the super-user to change object owners,       even if the current owner was
executingthe command and the new       owner was in the same group.  With roles such transfers are now       possible.

Most people don't know what roles are, but with them described in 8.1
release, we will have more people available to discuss in the future.

I think the not in the following should be now.  (limits can not be enforced)

Add per-user and per-database connection limits (Petr Jelinek) Using ALTER USER and ALTER DATABASE, limits can not be
enforcedon the 
 
maximum number of users who can connect as as a specific uesr or to a 
specific database. Setting the limit to zero disables user or database 
connections.

Also I think 
Allow TRUNCATE to truncate multiple files in a single command (Alvaro)
Should read tables or relations not files.
