So what you want is not what values are greater than some point 30 days ago 
which is what your previous query asked and answered, but the values between a 
point 30 days ago and today.  The easiest way is to use BETWEEN:

test(5432)aklaver=>\d big_int_test 

 Table "public.big_int_test"
 Column |  Type   | Modifiers 
--------+---------+-----------
 bint   | bigint  | 
 rint   | integer | 

test(5432)aklaver=>SELECT * from big_int_test ;
       bint       |    rint    
------------------+------------
 1287323899000000 | 1310799600

test(5432)aklaver=>SELECT 
	bint 
FROM 
	big_int_test 
WHERE 
	bint 
BETWEEN 
	extract(epoch from (date 'now' - integer '30')) 
AND
	extract(epoch from (date 'now'));

 bint 
------
(0 rows)


That being said, if your time values are the order of magnitude shown they will 
not meet the criteria above. Is the time value supposed to be seconds?
