Why is it your favorite? Which would you recommend for end users on multiple OSes? You mean what technology to use to build business logic? It just depends on your needs. I prefer to use Apple WebObjects for building web frontends to the db. Why? Because it is extremely powerful, free if you are able to develop on Mac OS X (it comes with the developer tools) and even if you have to buy a couple of Powerbooks and Xserves it may be cheaper then only the software license for one of the other big Java application server technologies. You can deploy it to every Java plattform because it's just a Java application, but it's build on and for Mac OS X. It completely frees you from thinking in tables, joins, selects and other sql stuff, well, at least nearly completely. I can switch my whole application including a couple of hundred MB database content in half a day (mostly the time to transfer the data) - I have done this two months ago from another dbms to PostgreSQL. It's just as "cool" as Ruby on Rails right now, not as fat and slow in development as most J2EE servers, you can deploy everywhere, I can develop on Mac OS X (yes, that's a reason for me, because it speeds up my work by a good percentage), it is extremely fast for development once you have the concepts and a good set of your own components in stock which you are used to. It's pure Java, so I can easily include third party tools like Lucene or others. It does one connection per application instance which keeps concurrent db tasks low. Also it has more than one working approach for multi language / internationalized applications. And, most important, it has a tool, which enables me to do things alone in days, other teams do in weeks with other J2EE tools: DirectToWeb - a rule and template driven dev plattform. You write the db schema, lots of "rules" how list, inspect, edit and search pages should look like and some basic html for wrappers and you can create an administration application faster as with everything I've seen so far. Including Ruby on Rails, PHP and other Java tools. But, to make this clear: the starting point to use it is VERY high. I had a couple of years doing WebObjects development when I started using D2W and it was good to have this background. Also you can build WebServices, rich Java client apps, can use Ajax for rich web applications and I have a tool that proved it's scalability, reliability and ease of use in a real high volume environment: the iTunes Music Store. For more information, send me an email and/or go to www.apple.com/webobjects>. (I hope the url is correct, I'm not online right now - sitting in the train to work ;-)) Ah, and if you download it for testing: go to one of the WO mailing lists and ask for some good tips for starters. It will help. Also, what do you think of having the database management system do all work (business logic etc) with the front end as a user interface vs. having N-tier with an application server handling business logic, and the db just accepting data. I prefer the second approach because it frees me from one specific database. I can use Oracle, PostgreSQL, MySQL, FrontBase, OpenBase, Sybase, MSSQL without changing one line of code (if I have avoided using custom SQL, which I mostly do) by just switching one framework. Okay, right, there are always some problems you have to solve, but they are nothing compared to what a PHP developer has to do to use different dbms as the one he develops on. This comes from having to re-invent the wheel every time a new user app needs to be created. You do something wrong if you don't build libraries of your basic and generic work over the time. This has nothing to do with the tool you use or the underlying dbms - it's just bad coding style if you have to re-invent the wheel for every app. For me and our customers it's more important to be able to switch the dbms than the application server. But, as with everything: YMMV. Ah, and for curiosity I'm just evaluating Ruby on Rails: it has interesting ideas and places itself somewhere between the fat J2EE app servers and the scripting languages PHP and Perl. It is more closely placed to WebObjects then I have thought on the first look, but is a bit easier to learn and not the big 800 pound gorilla of web development, with hooks, tool, templates, ideas and concepts for nearly every case. But in my opinion it lacks a couple of things, two of the most important for me are complete abstraction from the db (you may reach this with easy schemas and generic sql but not enough) and a working internationalization approach. It is lightweight and it would be interesting to build

Re: [GENERAL] What is your favorite front end for user interaction to postgresql databases?
I agonized over this decision when I migrated my application to PostgreSQL. I know Tony Caduto likes Delphi and he can give some good reasons for this (are you out there, Tony?). There has also been a good article recently about Ruby on Rails. For my purposes, I wanted to maximize cross-platform compatibility and decided on Java. I was advised (correctly, I think) to opt for SWT rather than standard Java Swing and ended up with Eclipse. I must say that Eclipse has not been particularly easy to learn - the documentation is quite uneven and the mail lists aren't nearly as helpful as with the PostgreSQL community. Also, Eclipse is changing so quickly that books have a hard time keeping up. Nevertheless, it is powerful and I've found it rewarding. To make things easier for others, I uploaded a basic Eclipse front end (without editors, views, and reports) to pgFoundry (Komo PostgreSQL Client). On the second question, I also like to have the database do as much of the work as possible. Michael Schmidt

Joshua is 100% correct about this; I do not know what you are seeing exactly, but your interpretation of it is wrong (unless someone has actually substituted pg_dumpall for pg_dump on your machine). My best theory at the moment is that somewhere along the way you (or someone) mistakenly created a bunch of stuff in the template1 database, and it is therefore getting copied into any new databases made by CREATE DATABASE. See the discussion of template databases in the manual. If this is what has happened, it's possible to drop template1 and recreate a pristine version from template0; there's a step-by-step recipe on techdocs IIRC. regards, tom lane ---(end of broadcast)--- TIP 6: explain analyze is your friend

Re: [GENERAL] What is your favorite front end for user interaction to postgresql databases?
On May 8, 2006, at 3:33 PM, Karen Hill wrote: What is your favorite front end for end users to interact with your postgresql db? Is it java, .net, web apache + php, MS-Access, ruby on rails? Why is it your favorite? Which would you recommend for end users on multiple OSes? This is totally dependent on the individual user's preference: - Many users comfortable with command line shells prefer psql (this is my choice). - Others who like a gui might use pgAdmin (or miriad others) - If interoperability with MSOffice is your main concern, I could see Access/ODBC being useful. As a general front-end, probably not. When you start talking about java v. .net v. php vs. ruby, that's a whole other ball of wax. That's a lot less about interaction, or even about databases and a lot more about programmer preference. Personally, I would recommend: Python + psycopg (highly interactive, great for complex scripts or even apps) Java + JDBC + Hibernate (I think JDBC sucks, but Hibernate totally rocks and more or less hides it from you) Shell + psql (great for simple reporting, automating dba tasks, etc. etc) Also, what do you think of having the database management system do all work (business logic etc) with the front end as a user interface vs. having N-tier with an application server handling business logic, and the db just accepting data. I currently have the opinion that N-tier is not as good as having the db contain the business logic via stored procedures. This comes from having to re-invent the wheel every time a new user app needs to be created. From personal experience (and others will disagree), I find putting logic in the database to be a bad idea. I only use stored procedures for triggers and the like, and I try to avoid those whenever possible. Here are my reasons why: - I don't like the PL/pgSQL language (yes there are alternatives, but they have their own drawbacks) - It's complex to test and upgrade (we actually wrote non-trivial infrastructure to automate both) - It's difficult to debug (compared to external languages like python or java) - It's difficult to profile, therefore getting good performance can be difficult I had a very complex system coded in stored procedures that performed poorly and was hard to maintain. It's now refactored into java/ hibernate code that's simpler to understand, performs much better and is easy to extend and maintain. Of course that's just my particular case and obviously YMMV. Stored procs could make a lot of sense if you have many different clients accessing the db in different ways and you want to strictly enforce business rules across all of them. I had no such requirements in my case. In any case I would strongly recommend doing the simplest thing that you can get away with. If your business rules can be fulfilled with grants, views and constraints alone, use them. -Casey ---(end of broadcast)--- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match

[GENERAL] exporting quoted CSV data from a query

It seems that the COPY command can do that for regular tables (COPY foo TO STDOUT WITH CSV QUOTE AS '"') but not for a query result. I could create temp tables in a script but it seems that there should be a simpler alternative. The command-line psql can obviously be used with an arbitrary query, but seems to fail on the quoting part--am I missing some option to psql that would put quotes around fields that contain the quote character, newlines, etc.?

When I did an initdb to initialize the cluster I made sure that the locale was C, and all the LC_ options in postgresql.conf are shown as C and "show all" shows them all as C in both databases. The locale in my shell is all en_US.UTF-8 so I tried setting LC_CHAR and LC_COLLATE to C in the shell before running the dump/restore and this did not work. Likewise with LC_ALL. I also tried exporting LC_CHAR and LC_COLLATE as C in /etc/sysconfig/pgsql/postgresql so that the server would run in the correct locale, just in case, but this did not work either. If it matters when installing postgres I recompiled the source rpm so as to make it an i686. Where do I go from here? Thanks.

Re: [GENERAL] intarray internals
Hi,
[I'm trying to share some of my thoughts about intarray contrib module.
If this is the wrong way to achieve this, please warn me. (Should I
first get in touch with Teodor Sigaev and Oleg Bartunov?)]
[6]
_int_same() in _int_op.c looks like making some redundant sorting and
not taking advantage of sorted arrays while comparing each other. Here's
the related code piece:
SORT(a);
SORT(b);
na = ARRNELEMS(a);
nb = ARRNELEMS(b);
da = ARRPTR(a);
db = ARRPTR(b);
result = FALSE;
if (na == nb)
{
result = TRUE;
for (n = 0; n < na; n++)
if (da[n] != db[n])
{
result = FALSE;
break;
}
}
IMHO, SORT() macro should be called after "if (na == nb)" block. (SORT()
doesn't remove duplicates.) Also, in the inner block, while comparing
two arrays, we can take advantage of sorting of arrays. While current
behaviour is like
if (A[0] == B[0] && A[1] == B[1] && ...)
we can replace it with sth like
if (A[0] == B[0] && A[ N] == B[ N] &&
A[1] == B[1] && A[N-1] == B[N-1] &&
...)
Attached patch tries to implement both behaviours mentioned above and
some minor hacking for arrays of 1,2 and 3 items.
Regards.

Re: [GENERAL] Using the REPLACE command to replace all vowels
Is there any requirement that you have to use REPLACE? Another (possibly better) way to do the same is by doing: select translate(your_string,'aeiou','') from your_table; In my experience that performs much better than regexp. I just ran it on a table of about 100K random U.S addresses and TRANSLATE outperforms REGEXP_REPLACE by a factor of 2. I would use TRANSLATE unless you need some of the heavier lifting that REGEXP can provide. > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Geoffrey > Sent: Sunday, May 07, 2006 3:54 PM > To: pgsql-general@postgresql.org > Subject: Re: [GENERAL] Using the REPLACE command to replace all vowels > > Magnus Hagander wrote: > >> Is there a way to make seperate replacements in 1 field in > >> one command in SQL? > >> > >> I need to remove all vowels (a,e,i,o,u) in a field.

No, Red Hat never shipped a RHEL version using 7.2.* (they went straight from 7.1 to 7.3). This is not unrelated to the fact that the community dropped support for 7.2, actually --- I'm sure we'd not be maintaining 7.3 anymore either, if I weren't personally on the hook to support 7.3 for RHEL3. Bottom line is there's no one out there maintaining 7.2 at all, and even 7.3 and 7.4 are really not getting anything but the most critical bug fixes. regards, tom lane ---(end of broadcast)--- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq

Re: [GENERAL] Google Summer of Code: Full Disjunctions
Hi Lee,
First, i have no knowledge of anyone that have implemented full
disjunctions(ever) aside
from the theoretical works of my colleagues.
With the exception of a corner case of it, that I believe was a simulation in
96.
(A. Rajaman and J.D. Ullman Integrating information by outerjoins and
full-disjunctions).
I'd love to hear about any implementation out there (aside from my colleagues
work, which
is mine also: cohen,sagiv, kimelfeld,kanza)
It can never be a binary operation since at the heart of the matter is that you
need to take
each subset of the relations and join them. i.e.:
A
B
C
A,B
A,C
B,C
A,B,C
and remove subsumptions, for example if you have {t_A,t_B} from the A,B join,
you will not include just {t_A} or just {t_B} in the result (subsumption).
Usually binary operations allow for a bottom up computation approach, but FD is
a TOP down approach
(Galindo-Legaria, C. outerjoins as disjunctions).
The answer what to do is a bit complex and part of it is in a paper that is
currently in review,
however:
You take the cyclic component, for example FD(A,B,C,D) and then join it with
another relation E.
It's not a trouble to write (A fd B) fd C but it will still have to be computed
as one computation -
FD(A,B,C).
Again, note that FD is only useful for cases you can't use natural outer joins.
So only if you have a cycle you use FD.
In my current implementation I do getfdr(A,B,C) to get the RECORD since with FD
you cannot
know in advance what will be the eventual RECORD (unless you save the RECORD
type for A,B,C
and A,B,C,D etc...)
then I run, for example, FD('A,B,C') as RECORD (a0 int, )
As you can see, you can now join other relations to the result, it's a standard
recordset.
So (FD('A,B,C') as RECORD (a0 int, ))
Here is an example of a RUN (ignore all the additional parameters):
select getfdr('rand_1_0,rand_1_1,rand_1_2');
getfdr
---
(a0 int4,a1 int4,a2 int4)
(1 row)
select * from odmbfd('rand_1_0,rand_1_1,rand_1_2',true,true,100,'random',10,10)
AS RECORD (a0 int,
a1 int, a2 int) natural full outer join rand_4_2;
a2 | a0 | a1 | a3
--+--+--+--
1 | | 1813 |
1 | | 3091 |
1 | | 316 |
2 | 2113 | | 2738
3 | | 2924 | 823
3 | | 2924 | 2735
.
.
select count(*) from
odmbfd('rand_1_0,rand_1_1,rand_1_2',true,true,100,'random',10,10) AS RECORD (a0
int, a1 int, a2 int) natural full outer join rand_4_2;

Hi Tzahi Since you seem to know about full disjunctions, I was wondering if you could answer this question: Can full disjunction be implemented as a binary operator? The algorithms I've seen for computing it seem to require that all input relations be supplied at once. Even in your message above you specified your example as FD(A,B,C) rather than say (A fd B) fd C. So I was wondering if the latter is possible? The reason I ask is that I'm currently trying to solve a problem that could in principle be solved using FD but it would fit into my current framework much better if it were a binary operator like the other joins.
