At my old job, we used PostgreSQL exclusively.  I was doing programming,
and it was great.

At my new job I've had a chance to work with SQL Server and Oracle.  I
don't like either of them from a SQL point of view.  They just don't
compare (at least for what should be easy stuff, like dates).  However,
they did have a strong point where I see PostgreSQL lacking at the
moment.

(hint, if you read the subject, you've guessed it)

E.g., Oracle 8i had a very nice management console (and from the glimpse
of 9i I got, it's even better).  You could look at things like database
schemas via a tree view, database physical layouts, user information,
and connection information.  (I don't have it in front of me at the
moment, so I'm sure there is more.)  In particular I was very interested
in the ability to view not only what query a connection was doing, but
which operations it did that took a long time to process (full table
scans, etc), which one it is working on now, and how long that one will
take.  I know a while ago someone was working on a way to get similar
kinds of information by attaching to the backends via gdb or something
equally dangerous/hackish/error-prone.  When would such an ability be
put into the system itself?  (I believe Oracle does it through system
tables, which I would think might be good for PostgreSQL, as it would be
hard, and slow, to query each backend every time.)

The other ability that Oracle had that I was impressed with was the
ability to do partitioning.  You could break a database up into pieces
and put them on, say, different drives, files, whatever.  This seems
like a good idea, and one I don't believe PostgreSQL has now.  I suppose
if you wanted to put a single table on another drive, you could move it
and symlink it, but that sounds like another dirty hack.  The other
thing it could do was take a single table and partition it into separate
physical files based on ranges in a column.  This could be used for
archiving, for example.

I know that there exist some pretty nifty third party solutions for
distributed and/or replicated databases (as listed on freshmeat.net),
but having a separate program responsible for it seems like a bad idea
for maintenance.

By now you are probably saying 'If you want these features, why don't
you implement them?'.  Well, I really wouldn't know where to begin. 
I've been on this mailing list since last July with thoughts of working
on PostgreSQL, but more than anything it's convinced me that I wouldn't
know where to begin. ;{  I've purused the source and even read a few of
the interals documents, but I still don't think I would know what really
needs to be done.  (Not to mention that this isn't a short list of easy
features.)

What are all your thoughts on these items?  Is PostgreSQL not at a point
where it should be thinking of this stuff?  I know you're adding some
new features and tweaks to the engine still, but I think the above
features would make alot of people more interested in PostgreSQL.  Many
people still think that open source products are just not
user-friendly.  I think these features would go a long way towards that.

Most of that information is now accessible via system views[1], so the
problem reduces mainly to writing a GUI for that.  In my mind, the problem
with writing such a GUI is that there isn't an easy choice of toolkit, and
most of us (active PostgreSQL developers) aren't well-versed in writing
GUIs.  Not that that's an excuse.

A point aside:  There's a MySQL GUI[2], which seems to be doing exactly
what you have in mind.

I believe that TOra is starting to have support for PostgreSQL now,
although I haven't managed to get it working for myself yet :-)

Some of the guys in our office use it for Oracle management and seem to
think pretty highly of it.  I know it supports MySQL  as well - can't
wait until the PostgreSQL support is fully available.

Regards,
					Andrew.

does it require KDE/Gnome stuff ?

Lib QT, but not any KDE, AFAIC tell.

It does, through qt3.

How about using Debian GNU/Linux? There's a tora package available. :-)

Re: Management tool support and scalibility
This email demonstrates how important GUIs are for database users. It seems 
like users are judging PostgreSQL on the ability to create, view and modify 
PostgreSQL objects.

Dave Page wrote a very nice GUI called pgAdmin II 
(http://padmin.postgresql.org).

It gives access to all PostgreSQL features. It is a must-have, especially if 
you want to use PostgreSQL 7.2 and its CREATE OR REPLACE FUNCTION which are 
supported.

I would also like to take the opportunity to point out (again) how important 
are on the to-do list : CREATE OR REPLACE VIEW, CREATE OR REPLACE TRIGGER. In 
addition, we would like to have a better CREATE TABLE AS with a choice of 
preserving/dropping linked objects (primary key, triggers, rules) and 
hopefully an ALTER TABLE ALTER COLUMN clause.

Why not concentrate on these very simple features before going further? This 
would bring a bunch of people from beginner tools (MySQL) as well as advanced 
ones (Oracle, MS SQL Server) to PostgreSQL.

Tried, and it looks great, but I've only managed to use it with MySql,
since the Debian package libqt3-pgsql is not available. Anyone knows
why?

I will try to later to build the package myself or to use tora via ODBC.

libqt3-psql is available...I think that's it. It's in non-us. I
haven't connected to a PG db with it yet, though.

Where did you guys find the Debian TOra package? I've hunted around and
can't seem to find it.

Sorry, I missed this one. libqt3-psql as all the other PostgreSQL stuff is
available only via non-US. Just look at
http://nonus.debian.org/debian/pool/non-US/main/libq/libqt3-psql/

It's not in testing aka woody yet. You can only get it from unstable aka sid
under pool/main/t/tora.

It links against encryption libraries - US export regulations.
