Обсуждение: Database diagram
I have a postgres database with many tables. How do I create database diagram? Are there any free tools available to create database diagram from pgsql database? Regards, Ganesan
I use Microsoft Visio. It also has reverse engineering. I ma having trouble with the refresh option which is quite frustrating but other than that it works fine. I used Erwin in the past and really like that but it is pricey and we already had a license available for Visio.

There is a free Perl script which is called something like pgautodoc which creates DIA diagrams from databases. Take a look for it on Freshmeat. ----- Original Message ----- From: "Ganesan Kanavathy" <ganesh@magnusquest.com> To: <pgsql-admin@postgresql.org>; <pgsql-sql@postgresql.org> Sent: Tuesday, January 20, 2004 1:38 PM Subject: [SQL] Database diagram > I have a postgres database with many tables. > > How do I create database diagram?

Dear Ganesan, pgautodoc (for dot output) + dot (from graphviz.org , creates postscript) + epssplit ( splits the postscript into multipage so that one can create poster size diagrams) works well for me. I have 45 tables in the database though. Regds mallah. Chris Travers wrote: >There is a free Perl script which is called something like pgautodoc which >creates DIA diagrams from databases.

Can anyone point me to a download for pgautodoc. I had a look on freshmeat (as Chris suggested) and couldn't find it. The only other thing I could find were RPMS that wouldn't go on my system.

Sorry, it is called postgresql_autodoc. It can be found at http://freshmeat.net/projects/postgresql_autodoc, iirc. I have been having trouble with it crashing (segfault) which is surprising since it is written in Perl (must be a bum CPAN module, but I will have to wait to figure out which one).

Just wondering which version of DBD::Pg you are using? When I upgrade from 1.22 to 1.31 (DBI 1.37), Perl was segfaulting (http://gborg.postgresql.org/project/dbdpg/bugs/bugupdate.php?628) for me when using fetch with bind_columns. GBorg developers cannot seem to reproduce the problem, and I have not had the time to try and bake a simple reproduction. They got back to me 1 1/2 months later, and still closed the bug. Kind of like the EDS crew which 'manages' our computer systems at work :-( Cheers, Rob -- 05:15:30 up 28 days, 19:01, 4 users, load average: 2.00, 2.02, 2.00

Hi Robert; I am using DBD::Pg 1.31. That may be the problem. Any suggestions regarding repairing this problem at the moment?

I never used it, but someone told me that imports data definition from PostgreSQL. You can try it. Luis Sousa

It works on any 7.x PostgreSQL-based database. Chris Travers wrote: > There is a free Perl script which is called something like pgautodoc which > creates DIA diagrams from databases.

Hey Chris, I just installed version 1.22 from cpan and it fixed the problem. From a CPAN prompt (if you use it) <install D/DW/DWHEELER/DBD-Pg-1.22.tar.gz>.
