I don't know. It works just fine here:

gerhard@gargamel:/tmp$ python
Python 2.2.2 (#1, Oct 18 2002, 03:24:30) 
[GCC 2.95.4 20020320 [FreeBSD]] on freebsd4
Type "help", "copyright", "credits" or "license" for more information.
>>> from pyPgSQL import PgSQL
>>> db = PgSQL.connect(); cursor = db.cursor()
>>> cursor.execute("select b from test where b is true")
>>> res = cursor.fetchone()
>>> res.b
t
>>> repr(res.b)
'<PgBoolean instance at 0x2826202c: Value: True>'
>>> res.b == 1
1
>>> res.b == 0
0
>>> if res.b:
...   print "true"
... else:
...   print "false"
... 
true
>>> cursor.execute("select b from test where b is false")
>>> res = cursor.fetchone()
>>> res.b
f
>>> repr(res.b)
'<PgBoolean instance at 0x28262020: Value: False>'
>>> if res.b:
...   print "true"
... else:
...   print "false"
... 
false
>>> 

If you still can't get it to work, could you please post a complete code
section that shows the problem?
