[1/4] Proposal of SE-PostgreSQL patches

[1/4] - sepostgresql-pgace-8.4devel-3.patch.gz

This patch provides PGACE (PostgreSQL Access Control Extension) framework.

It has a similar idea of LSM (Linu Security Module).
It can provide a guest module several hooks at strategic points.
The guest module can make its decision whether required actions should be
allowed, or not.
In addition, PGACE also provides falicilites to manage security attribute
of database objects. Any tuple can have a its security attribute, and the
guest module can refer it to control accesses.

(This patch is gzip'ed, bacause it overed the limitation of filesize.)
