Oracle is a decent product with all the features that you could want if you are an Enterprise and in addition they have the support for all that. Postgres has most if not all of them at this point, but if you want support you have to pick from one of many vendors.
Having used many RDBMS, one thing I very much liked about Oracle was the bitmap index. Very very useful for some performance issues that a b-tree cannot solve.
