	I rely on this working correctly in my backup system.  I dump about 
2.2GB of postgres nightly through a filter application which tests each 
block against the previous days' dump.  If the block is the same, it 
hard links the block to the previous days' block, else it encrypts the 
block and stores a new one:

rubik:~/bak/db 503% du -sk .
2751092 .

rubik:~/bak/db 504% du -sk *
2265096 20040322
2052    20040323
2372    20040324
2420    20040325
2204    20040326

rubik:~/bak/db 505% du -sk 20040621
2471368 20040621

        As far as I can tell, the right thing is happening here.
