Updates of SE-PostgreSQL 8.4devel patches (r1398)

I updated patch set of SE-PostgreSQL and related stuff (r1398).

[1/5] http://sepgsql.googlecode.com/files/sepostgresql-sepgsql-8.4devel-3-r1398.patch
[2/5] http://sepgsql.googlecode.com/files/sepostgresql-utils-8.4devel-3-r1398.patch
[3/5] http://sepgsql.googlecode.com/files/sepostgresql-policy-8.4devel-3-r1398.patch
[4/5] http://sepgsql.googlecode.com/files/sepostgresql-docs-8.4devel-3-r1398.patch
[5/5] http://sepgsql.googlecode.com/files/sepostgresql-tests-8.4devel-3-r1398.patch

I think the column-level privileges feature is now coming to
its goal, and will be submitted revised one soon.

It should be a time to start committer reviewing in SE-PostgreSQL also.
Anyway, I don't spare any my efforts it getting merged on v8.4.
Please make it progress.

List of updates:
- These are rebased to the latest CVS HEAD, including string reloptions improvement.
- Code cleanups in sepgsql/proxy.c and rowacl/rowacl.c.
- Documentation updates: add descriptions for newly added options on pg_dump, pg_dumpall and initdb
