Security...

Hi folks,

I'm trying to seriously restrict what a particular user can see within a 
database. Using various schemas, rules, groups and grants, I've managed 
to restrict them to only being able to _do_ what I want them to, but 
they can still _see_ the rest of the schemas, system tables, etc. I've 
tried revoking everything on public, pg_catalogs, etc, but you can still 
describe tables.

Anyone know how to stop this, or if it's even possible??

Cheers,


Steve.
