You use the chkpass type that I just commited to the distribution (finally.)
Here is an example of its usage.

darcy=# CREATE TABLE x (i serial, p chkpass);
NOTICE: CREATE TABLE will create implicit sequence 'x_i_seq' for SERIAL column 'x.i'
NOTICE: CREATE TABLE/UNIQUE will create implicit index 'x_i_key' for table 'x'
CREATE
darcy=# INSERT INTO x (p) VALUES ('hello');
INSERT 805247 1
darcy=# INSERT INTO x (p) VALUES ('goodbye');
INSERT 805248 1
darcy=# SELECT * FROM x;
i | p
---+----------------
1 | :SoLA2YFpQYV/I
2 | :Sg8CKkFqqTGec
(2 rows)

darcy=# SELECT p = 'hello' FROM x WHERE i = 1;
?column?
----------
t
(1 row)

darcy=# SELECT p = 'hello' FROM x WHERE i = 2;
?column?
----------
f
(1 row)

darcy=# SELECT i, raw(p) FROM x;
i | raw
---+---------------
1 | SoLA2YFpQYV/I
2 | Sg8CKkFqqTGec
(2 rows)
