[postgis-users] Selecting geocoded postal codes within a given distance ( miles for example )

Dear List,

How would one go about selecting the geocoded postal codes within given 
a distance ( say in miles ) of another geocoded postal code.  Finding 
the long/lat of the postal code we are searching around is simple ( no 
help is needed there ). I have read/seen the faq for postgis.  The 
example given  there using a bounding box doesn't really fit what I am 
trying to do exactly because I will be dealing with degrees 
longitude/latitude and miles ( the example in the faq uses meters 
exclusively ).

Thanks in advance for any help you can give.
