I've started using it only recently and I'm really pleased with it. I am using Oracle and Postgres constantly, and this was the first tool that worked really nice with both out of the box.
That said, it could use some more features, but all in all, very nice tool.
I've also tried OxDBE, but got feeling that it was not finished at all. Half of stuff was really annoying to use. I was never sure what was commited and what not. Adding columns to table worked sometimes, and sometimes it would just hang. In the end I was writing SQL by hand for even the trivial tasks. Not something I need IDE for. Hopefully they can improve it in the future, because other products from JetBrains are great.
