Suppose you have table:
create table a (
tag int,
info text
);
and you want controll user's depend on the 'tag' field value. I think
you can do following:
create view v1 as select info from a where tag = 1;
create view v2 as select info from a where tag = 2;
create view v3 as select info from a where tag = 3;
revoke all on a from public;
grant select on v1 to user1, user2...;
grant select on v2 to group gr1, ...;
