This is only tangentially related... are there any open source databases that implement materialized views as well as Oracle? Postgres is getting close but they're not there yet...
Can you expand on that, I'm unclear on what you consider "better"
Sure, what I think Oracle does better is it provides a lot more flexibility with how you can refresh your materialized views. Oracle has 3 ways that I know of to refresh materialized views; complete, fast, and partition change tracking, furthermore Oracle allows you to refresh on commit instead of have to manually do it or schedule a job to do it.
Although it has nothing to do with materialized views Oracle also has a built in scheduler, which can be used to do periodic refreshes (hourly, nightly, etc). You can achieve something similar with postgres by croning a SQL script.
To my knowledge postgres doesn't really have these things (other than in 9.5? you can do refreshes without getting an exclusive lock like in 9.4), although I could be wrong. I just wish Oracle wasn't so expensive.

I don't disagree that oracle has excellent materialized view support, but triggers and other strategies can go a long way also, I think Dan Chak did a really nice chapter on this in his book enterprise rails, that is also available online for free at http://dan.chak.org/enterprise-rails/chapter-12-materialized...
