What version are you using? It seems to work per spec in 7.4.
regression=# create function foo(name) returns bool as '
regression'# begin
regression'# perform * from pg_user where usename = $1;
regression'# return found;
regression'# end' language plpgsql;
CREATE FUNCTION
regression=# select foo('postgres');
foo
-----
t
(1 row)
regression=# select foo('not');
foo
-----
f
(1 row)
regression=#
