You could do this with views, on the order of create view secure_view as select * from base_table where access_allowed(current_user, ...); where you need to write an access_allowed function that implements your security policy (probably based on fields in the base table that are not reflected in the view, so it's not really gonna be "select *"). Then you grant access to the view but not the base table to the users. Also, take a look at http://pgfoundry.org/projects/veil/ and search the archives for past discussions of row-level security. regards, tom lane
