maybe this simple example helps you:
# create table colors (color text);
CREATE TABLE
# insert into colors select 'red';
INSERT 0 1
# insert into colors select 'red';
INSERT 0 1
# insert into colors select 'green';
INSERT 0 1
# insert into colors select 'yellow';
INSERT 0 1
# insert into colors select 'yellow';
INSERT 0 1
# insert into colors select 'yellow';
INSERT 0 1
# select count(1), color from colors group by color;
count | color
-------+--------
2 | red
3 | yellow
1 | green
(3 rows)
