Pretty picture of databases

The much loved
postgresql_autodoc -t dot
provides output that can be used as input by the graphviz tool. Which in turn can save the pretty pictures it draws to a pdf or, well... pretty much whatever format bats your whiffleball. Mighty impressive set of tools, and free down the whole chain. And then they gave me Visio, I added the ODBC driver and blammo: pretty database drawing. There's nothing free about Visio, but I have to say, the results are impressive.
