Re: [GENERAL] Int8 problem
Hi, I have intalled Postgres 7.0.2 recently on 3 normal PC with RedHat and Slackware to try its behavior but its working good. int8 thakes number much bigger then 10^13. And if the number is to big (about 10^19 ) it generate an error message (ERROR: int8 value out of range: ...) and don't insert it into the table.

I really appreciate Perl CGI because it's an amazingly fast development environment, much faster than any Java-based system I've seen. Just edit the script and test; there's no compiling, no copying or restarting of servers. mod_perl isn't quite as good, since you have to restart Apache, but Apache restarts instantly, so that's not a really serious concern. Java's compilation time and the regular need to restart the Java environment really slow down development work. (I've yet to find a servlet system whose "automatic reload" feature truly works as advertised.) I've also noticed that people who don't know Perl really tend to underestimate how many really good Perl developers there are. - Tim

Replication Server "When we announced our ongoing development of the PostgreSQL Enterprise Replication Server (eRServer) last month I had no idea how great the interest and demand for this would be." states CEO Geoff Davidson. "We have received dozens of inquiries from customers, competitors, and development companies asking for more information. Today I'm very pleased to announce that the first prerelease version of eRServer has been delivered for testing." "At the moment we are limiting our test groups to our existing Platinum Partners and those clients whose requirements include these features." advises Jeff MacDonald, VP of Support Services. "We expect to have the source code tested and ready to contribute to the open source community before the middle of October. Until that time we are considering requests from a number of development companies and venture capital groups to join us in this process." Davidson explains, "These initial Replication functions are important to almost every commercial user of PostgreSQL. While we've fully funded all of this development ourselves, we will be immediately donating these capabilities to the open source PostgreSQL Global Development Project as part of our ongoing commitment to the PostgreSQL community." This initial release of eRServer is intended to support companies and individuals in development of applications that require the following functions and capabilities: * Server to Client Replication * Data Merge [PostgreSQL to PostgreSQL] * Data Converge [ODBC/other to PostgreSQL] * Mirroring & Disaster Recovery * Test Regions for development & scenario activities * Full & Differential Replication [backup / update] * Data Hierarchy Replication [need to know distributions] Jeff MacDonald Marc FournierThomas Lockhart * 1 877 542 0713 * 1 877 542 0713 * [EMAIL PROTECTED] * [EMAIL PROTECTED] * [EMAIL PROTECTED] Geoff Davidson eRServer Info: * 1 416 410 4124 ext. 1 www.eRServer.com * [EMAIL PROTECTED] For a copy of this document in PDF format go to: http://www.pgsql.com/press/Pgsql_Inc_Press-5.pdf

The breakup follows Informix's March acquisition of Ardent Software Inc., a data warehousing vendor in Westboro, Mass. The as-yet-unnamed business intelligence and e-commerce venture will be headquartered at Ardent's facility, while the database company - to be called Informix Software - will be based in Silicon Valley. Informix previously said it would have 3,900 to 4,000 employees after last month's layoffs and the planned hirings of some new sales and support workers. Last week, the company said the two separate companies will have a combined workforce of about 3,400 people. In addition, the company warned that it expects to report a third-quarter operating loss of $15 million to $24 million, which will be widened by restructuring charges and other one-time expenses totaling as much as $90 million. Meanwhile, the Informix Software database operation will try to breathe new life into the company's core database technology. The database company, which expects revenue of $780 million to $800 million this year and will start out with 2,300 employees, is expected to be run by Jim Foy, another former Ardent executive who was named a senior vice president at Informix last month. In an attempt to revitalize its database sales, Foy said, Informix has a new technical architecture on the drawing board, after having recently completed a detailed analysis of its existing technology. One More Chance Consulting firm AMR Research Inc. in Boston described Informix's breakup move as "a last-ditch effort to reinvigorate" the company's database business. The move may have come too late to help Informix take back much database market share from Oracle Corp. and other rivals, AMR said. But, the company added, the new management team from the Ardent side of the company "is showing it can make tough decisions and is ready to fight." Other recent stories by Dan Verton Sendfeedback

In a nutshell, they said Java > will phase out most large perl implementations (new clients tend to be > developed in java, old code is redone, etc.) The place I worked at over the summer did something similar. They have a large existing infrastructure written in Perl/CGI + Apache, with the odd thing using a Postgres backend. This was all running on a big Sun E450 (obviously running Solaris). When I started working, they had been moving things over to Java Servlets - using JServ. They were also getting much better hardware. However, the Servlets seemed really unstable. JServ would die for no apparent reason. It seemed like a lot of the staff felt that perhaps moving to Java was a mistake. Whether their problems were the fault of JServ, Java, or incompetent programmers/admins, I don't know. (BTW, Postgres was rock stable. We never had any problems with it). So I really haven't had enough experience with Java Servlets, since Perl is more than sufficient and I know it works well. I personally do my web programming in mod_perl, usually with DBI and Apache::DBI. I love Perl, and I've had very few problems. I agree with someone who mentioned mod_perl is tough to get into - it takes a while to get up to speed. As for PHP being embedded into HTML, the same thing is possible with Perl - but you also get TMTOWTDI. The following all embed Perl in HTML, to some degree: HTML::Template HTML::Embperl HTML::Mason (as someone mentioned) ePerl And probably a few others I haven't heard of. You're free to pick and choose whichever suites you best. I'd recommend Perl, but it's really just a matter of personal taste.

So softupdates should be ok as long as postgresql is issueing fsyncs, if you're running postgresql in async mode, then it's probably better not to use softupdates. Also, since running postgresql in sync mode will basically cause the negation of most softupdate benifits with the exception of tempfiles, doesn't postgresql differenciate between system files and tempfiles? -- -Alfred Perlstein - [[EMAIL PROTECTED]|[EMAIL PROTECTED]] "I have the heart of a child; I keep it in a jar on my desk."

[GENERAL] Encrypting fields with a one-way hash
Hi,
I'm new to PostgreSQL, but have installed it on a RedHat 6.2 box. We are
currently trying to migrate our existing MySQL applications to PostgreSQL,
but the differences in syntax are presenting a few problems.
My main stumbling block is the apparent lack of a function to form a hash
(or other one-way encrypt) of a password to enter as a field in the
database. The old SQL looks something like:
> INSERT INTO Users (Name, Password) VALUES ('John Smith',
PASSWORD('mypassword'))
This works because "PASSWORD" is an internal function in MySQL. Is there a
similar function in PostgreSQL, or some other way of achieving the same
effect? The data itself is not being moved over, so there is no need for the
same algorithm to be used.
Thanks for any and all help,
**

Hi J and Michelle.
I'm curious to try this also - I have a friend who has done alot
of work with Zope/Pg and so I have been looking over his shoulder
for awhile...I'd like to have a go myself.
I have written a slew of applications for my company's Intranet in
perl/CGI/DBI. This is also a high octane solution. Of course I am
a perl fanatic (it's like C for those of us with severe time constraints
and limited abilities ;-)
My src is public domain but not yet ready for prime time (too few comments
and too many mistakes, sloppy coding). I would send a sample tho if
you (Michelle) were interested.
Ciao,
Tom

Re: [GENERAL] web programming
I use PHP with my Postgresql and haven't hit a limitation yet. As far as perl goes, I know some web develoeprs for a consulting firm that use Solaris and they are pretty tight in the industry. Their advice to me was that if I already don't know Perl, don't learn it. They said to take the Java route. They also were fond of PHP. In a nutshell, they said Java will phase out most large perl implementations (new clients tend to be developed in java, old code is redone, etc.) As for me, I was thinking about trying java server pages, just for the fact that you can technically use Java for every level of development.

It can cause problems because softupdates makes meta data changes (in this case file creation/removal) asyncronously, the same actually happens with most other logging filesystems that don't support transactions. Since afaik postgresql doesn't use lots and lots of tempfiles you may want to play it safe and not use softupdates. -- -Alfred Perlstein - [[EMAIL PROTECTED]|[EMAIL PROTECTED]] "I have the heart of a child; I keep it in a jar on my desk."
[GENERAL] FreeBSD Softupdates??
Just a quick q. Does anyone know what effects FreeBSD's 'softupdates' would have on the /usr/local/pgsql/data filesystem. Would this help performance, or would it be a shot in the foot?? -- Dale Walker [EMAIL PROTECTED] Independent Computer Retailers (ICR) http://www.icr.com.au ICRnet http://www.icr.net.au
[GENERAL] Incremental backup of logfile
Hello, it is possible to save the transaction log of PostgreSQL? I would like to store daily logs and sync a second server with this daily log (it is enough for this purpose). Kind regards Andreas.
