Thanks Tom for the quick Update. 

Can you please point me to a link or give the list of OSes where ASLR is 
officially supported by Postgres?

Regards,
Joel

Not on Windows --- since that OS doesn't support fork(), it's too difficult to 
get different child processes to map shared memory at the same address if ASLR 
is active.

If that feature is important to you, use a different operating system.
