Serial is no datatype, but an int4 with a default. I don't know if the default is reverse engineered correctly, I'd recommend to change it manually to "serial". > Is it possible to teach PowerDesigner to reverse engineer correctly ? Probably not. pgAdmin has special treatment for int4/default to detect a serial; PD as cross platform tool is not smart enough. Similar about inheritance; I don't even know a way how to design this in PD (in PD 8.0, I doubt 10.x is better). > Or can anybody recommend me right tool which works correcty? You could try ERwin, but I doubt you will be luckier there. Regards, Andreas

Case Studio looks like it has better support, but I've not had the opportunity yet to try it yet. http://www.casestudio.com/enu/databases.aspx -- Best Regards, Simon Riggs

In order to get it to work I would have had to write a set of perl scripts to massage the output, so I ditched it instead for Case Studio and haven't looked back. It's not perfect but it is plenty good for even complex schemas; enough so that really my only gripe is that it doesn't run on *nix :-( -- Robert Treat Build A Brighter Lamp :: Linux Apache {middleware} PostgreSQL
