An earlier post referenced a bunch of Oracle performance pages. One of

indicates that on Linux 2.4 kernels one can use Direct I/O (if you DB

Does Postgresql support the use of Direct I/O or Raw I/O? Base on

it would seem that not using one of these "wastes" alot of RAM.

Just curious .... I am a couple of months away from production.
