Folks,

Of course, while I was editing press releases at 2am, I started thinking about 
our next version.   It seems certain that the next release, in 6-9 months, 
will have at a minimum the Windows port and ARC, if not Slony-I as well.

Given all that, don't people think it's time to jump to 8.0?    Seems like 
even 7.4 is hardly recognizable as the same database as 7.0.

I'm posting this to both Advocacy and Hackers because I think that some people 
will have rather different points of view on the issue.   But I wanted to 
start a discussion early this time.  No flamewars, please!   We all want 
PostgreSQL to be the best possible database.

It seems a little premature to speculate on what features may or may
not be present in 6 to 9 months time. Why make this decision now, when
we don't even know what will be in the next release, rather than at
the end of the development cycle?

As has been said before, many people think that a Windows port is the
least interesting feature ever to happen to PostgreSQL, so you're going to
have to come up with better reasons.  Also note that most major number
changes in the past weren't because the features were cool, but because
the project has moved to a new phase.  I don't see any such move
happening.

Yeah, I'm more interested in ARC and replication ... and the SQL 
standardization that just went into 7.4.

Now that is interesting.  I missed that.   Can you explain how that worked 
with 7.0?

What happens if Postgres hits 7.9 but still hasn't reached the next 
phase? :)

Hello,

  If Win32 actually makes it into 7.5 then yes I believe 8.0 would be
appropriate.

Discussion like this tends to be more for just before beta, once we have

It might be interesting to track Oracle's version number viz. its
feature list. IOW, a PostgreSQL 8.0 database would be feature
equivalent to an Oracle 8.0 database. That would mean:

1) PITR
2) Distributed Tx
3) Replication
4) Nested Tx
5) PL/SQL Exception Handling

IMHO, a major version number jump should at least match the delta in
features one finds in the commercial segment with their major version
number bumps. Otherwise, I suspect it would be viewed as window
dressing...

Could be wrong, though...

If wishes were fishes...  Shouldn't we see what interesting features
actually _do_ make it in?

If Win32 support does get ready, and we get recursive queries (I'll
point out different TODO items :-)) and Slony-1, PITR, and cache
improvements make it in, then perhaps it's time to call it 8.0.  A
"cvs update -Pd" doesn't get me that yet, so it seems early.

I'd _almost_ buy the story that 7.4 should have been called 8.0,
although that _didn't_ happen because it 'just missed' PITR and Win32.

The amusing approach would be to jump straight to 8.1 :-).

We stopped crashing in 7.0, or was it 6.5 --- that was our milestone, I
think.  :-)

Of these PITR seems *by far* the most important. It makes the difference
between an enterprise-class database capable of running 24x7 with disaster
recovery plans, and a lesser beast that needs to be shut down for cold backups
periodically.

Features like Nested Transactions and Exception Handling are "would be nice"
features. Especially for pre-existing code-bases. But for new projects they're
not things that make the difference between measuring up and not.

Besides, Oracle 8 had Replication the way Mysql has transactions... It a
recently bolted-on addition that only worked in limited cases until a few
rewrites later.

Oh, and yeah, a win32 port. Yay, another OS port. Postgres runs on dozens of
OSes already. What's so exciting about one more? Even if it is a
pathologically hard OS to port to. Just because it was hard doesn't mean it's
useful.

I don't call porting Postgres to run well on something like 40% of the 
world's servers (or whatever it is) "just another port".

It could conveivably double Postgres's target audience, could attract 
heaps of new users, new developers, new companies and put us in a better 
position to compete with MySQL.

I think it's actually a necessary port to keep the project alive in the 
long term.

Absolutely!  In addition, even if you don't consider win32 a platform to 
run production databases on, the win32 port will help developers who 
work from windows boxes, which is the certainly the most widely used 
desktop environment.  My former company would have loved the win32 port 
for exactly this reason, even though most of our servers were FreeBSD / 
Linux.

That's a misleading extrapolation. If people wanted to run an open source
database they could just as easily run a Solaris, Linux, or BSD server to run
it on anyways. I assure you 40% of the worlds servers will not switch from
MSSQL to Postgres the day the win32 port comes out...

The reality is it just doesn't happen that way. Postgres isn't the first major
unixy software to get ported to windows. Emacs, Gcc, Mozilla, Gimp, even X all
have windows ports. And they're not dead ports either, they have significant
user-bases. But they don't make much of a dent compared to the much larger
entrenched Unix user-base and they don't change the nature of the development
much.

Oh sure, it'll be useful. But it doesn't make the difference between different
classes of software. It'll still the same Postgres with the same set of things
it's capable of handling once you get it running. 

If you need 24x7, scalability to n terabytes or x transactions/s, guaranteed
data integrity in the face of various failures, none of the checklist items
you'll be looking for will be win32 support. PITR will probably be a factor in
meeting any of those requirements.

In any case, my post was mostly a troll, there's not really much point in
arguing with it. They're all useful features and I hope they're all in the
next version of postgres, whatever version number it's given :)

Statistics is a tricky thing. IMHO, there are plenty of things that are much
more important than win32 port.

And my former company produced software that ran on Windows and *nix. We 
would have loved to be able to ship PostgreSQL as our reference 
database, but could not because there was no native Windows port.

We've been over this ground before. It might not be important to some 
people but it is important for a hell of a lot of others.

Absolutely correct.
PostgreSQL runs on so many platforms. I cannot see a reason why we 
should put effort in an inheritly nasty operating system which will 
cause A LOT of pain in the future.
I can already hear the question we will have to face ...
People using PostgreSQL are not MySQL or Access people - they know why 
they are using Linux. I have seen somebody asking for Windows once or 
twice in 4 yours. Is it worth the effort?
Of course, many people use Windows - I can understand that for desktop 
PCs but personally I am in a bit different situation. We support 
PostgreSQL which means that people will cut my head off if something 
does not work. I don't trust Windows and I don't want to hunt bugs in 
PostgreSQL which are caused by an inferious and inheritly nasty 
operating system.

As far as versioning is concerned: I am not in favour of pumping the 
version number to number. Here in Austria we call those things 
"versionitis" - it is a Windows-disease and should be cured.

We have never lost against a different database because of a lower 
version number.

I'd make 8.0 a "network release" meaning that 2pc, replication and 
things like that are supported.

	Regards,

		Hans V1.0

Dear Greg,

In your opinion, why did MySQL capture so many users quickly?

Is it because MySQL offers a nice and powerful solution? No, on the converse, 
everyone knows that MySQL is not a reliable database. To some extent, MySQL 
is not really ACID compliant. It cannot parse large queries with LEFT and 
RIGHT joins. It does not offer reliable ODBC. And it does not evolve very 
quickly. it does not support Unicode. There are no server-side languages. 
etc...

So why did MySQL succeed? In my opinion, because Php and MySQL were both 
available on Apache servers (GNU/Linux) and on home stations (Win32). Simple 
as that.

This kind of cross-needs-effect is called a ***portfolio effect***. The 
portfolio effect is the ***central marketing strategy*** of Microsoft when 
releasing OS and Office suites together.

Because your Grand-mother owns a Win 95 station, she sends you files under 
PowerPoint 95, in turn you invest in Office 2000 and send Excel 2000 files to 
your brother, who in turn invests in Office XP and prints Word XP documents. 
[<---Future readers in 200 years: all these names used tp be trademarks from 
Microsoft in a time when a few people tried to lock-up ideas.-->].

And you end up with everyone upgrading Office and Windows. Now, without being 
pretentious, I would like to remind this simple idea:

***Who lives by the sward, dies by the sward***

If we apply the same strategy as Microsoft or MySQL, PostgreSQL can conquer 
the whole market. Not 1% like today, but 60% or more like Apache. Because we 
are a community.

If you do not believe reaching 60% of market shares is possible, let us assume 
that a PostgreSQL Win32 native port is available in 6 months. Immediately, 
the following bundles would appear:

- PostgreSQL + PhpPgAdmin + pgAdmin -> a potential of 1 million users
- Apache2.0 + Php5 + PostgreSQL -> a potential of 5 million users
- OpenOffice + PostgreSQL -> a potential of 10 million users
- Some MS Access replacement -> a potential of 2 million users
- there are many others...

For me, this makes 60% of the market at least.
A 1% to 60% is not a small difference, it is a real gap.

Best regards,
Jean-Michel

Don't forget that success isn't always connected with technical things 
(very good example is MySQL :-)) - PostgreSQL needs a good marketing, 
clear strategy and identity. But for sure Win32 port will be a huge step.

There are other databases which have Win32 native version and aren't so 
popular (like Firebird...)... So my proposition to PostgreSQL's team is 
to think also about SMI -> Strategy Marketing Identity...

The real fun would be to let it start as 8, then 8.1 and so on ...

Personally I thought that the 6.5->7.0 jump was a mistake ... but that's
water over the dam now.

I would be willing to call a PG release 8.0 when it has built-in
replication support --- that would be the sort of major-league
functionality jump that would justify a top-number bump.

There are not that many other plausible reasons for a top-number bump
that I can think of right now.  PG is really getting to be a pretty
mature product, and ISTM that should be reflected in a disinclination
to call it "all new".

You can be dead certain that a Windows port will not be sufficient
reason to call it 8.0.  Perhaps 6.6.6 would the right starting version
number for that one ;-)

ACK.
A major release (for me) implies some really major improvement.
Replication would be such a thing.

BTW: is there anything working yet in this direction ?
I know several "userland" implementations (w/ triggers), and I also
doing symetric (masterless) replication in my middleware framework, 
but when will pgsql be able to do it by itself ? 
And when will probably load balancing come ?

hmm, which commerical RDBMS (beside oracle) provide this already ?

All replication work is being done as add-ons because then people can
choose the replication solution that works best for them.  We don't
think a single solution can fit all needs.

There is only one production and shipping replication that does not
require triggers that I know of and that is ours (Command Prompt).
It is also not a userland app but actually part of the PostgreSQL engine.

There is also ERServer which was first (?) but it tends to be a bit
of a beast to maintain.

There is Slony-I which is showing promise but is a Trigger based option.

Others include Peer Direct (Which I believe is query based) and 
PgCluster which is query based.

Each solution has pro's and cons. Slony-I for example appears to be 
better when doing mass updates or deletes than Replicator.

On the argument of significant features for 7.5:

Win32 Native
PITR
Nested Transactions
Background Writer....

Where do the come in ? 
Hast the postmaster to be patched and recompiled ?

Is there anywhere an overview about them ?

Ah. Has pgsql to be patched for that or can it be simply dropped-in
like external (C) functions/procedures ?

What about lazy replication (i.e. when some node is running but not
online for a while), masterless replication (all nodes are equal)
or journaling ?
My application/framework-level solves this, but 
a) requires some special table layout (first attrs have to be inode+mtime), 
b) not suited for high update-rates (relly too slow for that)
but it is already working quite stable for several years :)

yeah, on subsequent mass-updates on just one host per table at certain time,
my stuff is also good, since it works w/ batching. but when multiple hosts
do heavy updates on the same table, it may run into conflicts.

Re: [HACKERS] Not 7.5, but 8.0 ?
This probably has been discussed and is probably a very minor point, but 
consider how many more years we want to be able to use the <single 
digit>.<single digit> major release numbering.

Assuming 1 year between major releases (7.3.0 -> 7.4.0 = +- 1 year), 
then we have 7.5-9.9 = 26 years = up until +- jul 2030. if we skip to 
8.0 now, then we have up until 2023.

Also we have 1 more chance to skip major number: 8.x -> 9.0. Imagine 
what features will there be in 9.0 that is ground-breaking enough. 
Because after that, we don't have any more major number to jump into 
without going into 2 digits.

I personally don't see the major number as a very magical thing. Look at 
Linux for example. People still see 2.6 as very different/ahead compared 
to 2.4...

Of course we can, I didn't say we can't. But double digits are sometimes 
undesirable because it can break some things. For example, a simple 
shell or Perl script might try to compare the version of two data 
directories by comparing the content of PG_VERSION stringwise. It then 
concludes that 7.10 is smaller than 7.4.

Granted, the script itself is faulty, but since some other OS projects 
(like Ruby, with the same x.y.z numbering) do guarantee they never will 
have double digits in version number component than people might think 
the same too and thus the habit of stringwise version comparison continues.

Oh?  What's their plan for the release after 9.9.9?

In practice, non-broken bits of code don't make such an assumption,
as there have always been lots of projects with double-digit version
components.  A quick grep for locally-installed packages finds

autoconf-2.53.tar.gz
binutils-2.10.1.tar.gz
bison-1.875.tar.gz
cvs-1.10.7.tar.gz
emacs-19.34b.tar.gz
expect-5.38.tar.gz
gcc-2.95.3.tar.gz
gettext-0.11.5.tar.gz
ghostscript-6.50.tar.gz
lesstif-0.89.9.tar.gz
lsof_4.47_W.tar.gz
make-3.79.1.tar.gz
mysql-3.23.29a-gamma.tar.gz
netcat-1.10.tar.gz
ntp-4.0.99k.tar.gz
procmail-3.22.tar.gz
sendmail.8.12.11.tar.gz
tar-1.13.tar.gz

IMHO trying to avoid double-digit component numbers is just silly.

As for Ruby, it probably won't expect > 9.9.9 in any foreseeable future. 
It takes +- 10 years to get to 1.8.1. Same with Python. But Perl will

You cannot seriously propose that the version number in itself should
prevent a 10th bugfix on some branch just to satisfy the possible existence
of an incorrect version number parser somewhere?

IMHO a discussion concerning rules controlling when and why things should be
major versus minor releases is needed rather than invalidating the
significance of major/minor/bugfix altogether.  What you propose is very
close to suggesting one single number ranging from 001 to 999. I don't think
that will meet much sympathy either.

Kind regards,

Thomas Hallgren
