Thats not true:

test=> create table ints (i int);
CREATE TABLE
test=*> insert into ints values (2);
INSERT 0 1
test=*> insert into ints values (3);
INSERT 0 1
test=*> select avg(i) from ints;
        avg
--------------------
 2.5000000000000000
(1 row)

test=*> select stddev(i) from ints;
         stddev
------------------------
 0.70710678118654752440
(1 row)
