If we suddenly wanted to optimize Postgres for performance the way
Oracle does, we would be a lot more keen on the O_DIRECT approach.
This isn't ever going to happen, for the simple reason that we don't
have Oracle's manpower.
I have wondered (somewhat fruitlessly) for several years about the possibilities of special purpose lightweight file systems that could relax some of the assumptions and checks used in general purpose file systems. Such a thing might provide most of the benefits of a "database kernel" without imposing anything extra on the database application layer.
Just a thought - I have no resources to make any attack on such a project.
