Обсуждение: security on line by line basis

hey folks

 is there a way to set postgres 6.3 up to do security on a record by
record basis?
  See what i am doing is createing a database that needs several
levels of security
     admin  - total access to databasee
     sub-admin - total access to database except for the first 2 and
last 2 entries in the database
     group-admin - access to only a piece of the database based on
criteria

  can i create a rule and have grant and revoke privs based on that
rule?

You can create 3 tables, and then make 2 views: one for the admin, one
for the sub-admin, using union's....
