The other thing is that some oracle features only work on exadata or other engineered systems. The hybrid columnar compression for one and query offload as well as some forms of the in memory stuff. The problem is that these are very high end features and most of us live happily without these. Postgres is going after the bread in the oracle db market while exadata is the exclusive cheese shop. Much smaller market even if the margins are better.
I wouldn't be so sure. Oracle has deep pockets, and I'm not sure there's a reason why anything PostgreSQL wants to roll out they can't pay to prioritize and have done sooner.

No argument there.
The problem commercial businesses have when it comes to open source is that you might be able to reduce customer take up, by you can't compete with it like you would other businesses. In the closed source world you can purchase a company and shut down its product and thus kill off the competition.
As Microsoft have found, with open source software, that's not possible.
The other unfortunate thing for Oracle is that when they attack Postgres they have to publish lists of competitive advantages. All this does is give Postgres developers a todo list, and they then work towards implementing the features that matter.

We have hit peak Oracle. From this point forward it's going to be hard for Oracle to regain momentum. Expect a lot of FUD against Postgres - the more you see, the more worried you know Oracke execs are becoming.
