I use dbWrench (dbwrench.com). It's not free, but they do have a free trial version so you can see if you like it before you buy it. It's also not expensive compared to many of these sorts of tools. It also runs on all 3 major platforms (it's written in Java) and the developer is responsive if you find a problem.
If money is no object, you can look at Power Designer (by Sybase). I used to use it years ago and liked it even if it was MS-Windows only, but the price has gone up so much only companies can really afford it now, IMO.
