One more feature that I am not sure PostgreSQL has is, row-level, 
column-level security. Oracle call this Label-Security in which you 
define a policy for certain columns so that they are not visible to 
un-authorised users during SELECT queries. This is an important security 
enhancement. One other feature is called Fine-Grained Auditing. Ability 
to track user activities. I hope this is in PostgreSQL in one form or 
the other.


I want to know your views on this.


Do you know the Security-Enhanced PostgreSQL project?

It provides fine grained mandatory access control on database objects,
integrated with the security policy of the operating system.
This feature includes row- and column-level access control as you said.

Linux Weekly News provides a good abstraction:

What is the definition of Fine-Grained Auditing?
SE-PostgreSQL also provides an audit enhancement in row- and column-level.
It can be controled AUDITALLOW of DONTAUDIT rules in the security policy.

See the following URL, to know more details.
There are several documents, SVN repository and RPM packages.

Both of these exist or can be assembled from other pieces.
