In SELECT version(); it should say smth about the architecture.
If this does not help, write a C function that checks the sizeof(void *), and 
compile it in both systems (64,32), and then install it on both postgresql's.
Then at calling time, check its value, if its 4 then it is on a 32 bit system,
if it is 8 then it is on a 64 bit system.
