Configurable security? Sounds great to me.
This is exactly how Teradata implements this; they even present you with
a choice of views to load ontop of the catalog tables. Secure/Not. You
choose.

That sounds OK for this situation. Doesn't it Merlin?
That would open up the market for pay-for add-ons to PostgreSQL. It
would also encourage packaged app vendors to port their code to
PostgreSQL, in the knowledge that their source code would be secure.
