create database diagram from pgsql database?

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.

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.

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).

Best Wishes,
Chris Travers

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

Hi Robert;

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

Did you already tried dia?
I never used it, but someone told me that imports data definition from
PostgreSQL. You can try it.

There are several such tools:

http://www.rbt.ca/autodoc/
dbVisualizer - gratis, but not Free

and many others. Search in freshmeat.net and google.

Postgresql AutoDoc - Default branch
by Rod Taylor - Thursday, July 19th 2001 11:15 PST     Section: Software

About:
Postgresql AutoDoc has the ability to output XML, which can be loaded
into Dia to create a UML diagram of the database (complete with table
relations and descriptive information), an HTML form for further
detailed information, GraphViz .dot output, and Docbook 4.1 style SGML
for inclusion with project documentation as an appendix. It works on any
7.x PostgreSQL-based database.

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>.

Cheers,
Rob
