What you need to do is to deny access to the underlying table, but
create views containing each user's particular data and make those views
readable by the appropriate users. Updatable views are not yet
implemented, so you will have to do some roundabout work to enable
users to update data - perhaps have them store data in intermediate locations
from which some other process transfers the data into the underlying table.
You probably need to be running 7.1 to do this effectively.
