Given absolutely zero information, are both platforms the same
number of bits? 32-versus 64-bit? The alignment needs for 64-bit
could result in needing more space. Another alternative is that
the order of data insertion caused a bigger index. What happens
if you run a REINDEX on both DB's to the index sizes?
