So what can I say? One of the phrases I hate most is “We’ve had problems with that.” I have seen that, or some form of that, question used as an excuse to not try new features, to not use best practices, keep a head in the sand, stick to Oracle7 features, etc.

As an example, in my early days with data modeling, I once created a new schema. It wasn’t a very big schema; probably 10 tables or less. I spent a lot of time doing the analysis to make sure I got the data structures correct. The ERD was sent around and got approval from everyone.
