SELECT attname, description FROM pg_class, pg_attribute, pg_description WHERE 
pg_class.relname = 'codes' AND pg_class.oid = pg_attribute.attrelid AND 
pg_attribute.attnum > 0 AND (objoid = pg_class.oid) AND (attnum = objsubid) 
ORDER BY attname;

The above will display the following:
 attname  |       description
----------+-------------------------
 amt      | Code Amount
 auto     | Auto Deduct Flag
 code     | Code
 deduct   | Deduct Flag
 descript | Code Description
 gl_acct  | GL Account Number
 method   | Calculation Method Flag
 name     | Program Internal Name
 percent  | Percent Value
 type     | Code Type
(10 rows)

There are many combinations of this. It just depends on what you want.
