This is essentially true, although it makes a lot more sense for things 
that are a lot larger (full ISO's like Linux distributions) and have a 
higher desirability than "official" avenues to get to them.  That's not 
to say that it shouldn't be offered, it's just a niche thing & is 
generally time-sensitive (i.e., it does the best when there a lot of 
people using it & the time most people use it is when something is "hot 
off the presses").  PostgreSQL is sufficiently small and has high enough 
availibility that either you won't have to think twice about downloading 
through standard avenues or BT won't help you.
