Well, a view is the easiest thing, grant permissions to the view and
revoke them from the base table.
However, if you actually want functions, you should be able to say
something like:
create table testtable(a text, b int);
create function gettesttable() returns setof testtable as ' select * from
testtable where a = SESSION_USER;' language 'SQL' security definer;
This example is one that really would make more sense as a view, but
imagine that the function was plpgsql and actually did something
interesting.
What have you tried so far?
