I install PostgreSQL 7.4.2 today without changing Cygwin install. Initdb 
works fine : initialization is good !

I tried it and it actually only happens on 9x.  I found that postgres
tries to shmat to an address which I have no idea about where it comes
from.  The problem with that address is, that it's neither a multiple
of SHMLBA, nor does postgres call shmat with the SHM_RND flag.  For some
reason the address is ok on NT.

So, Jason, do you have an idea why that happens?  Two questions come to mind:

- How does postgres evaluate that address and why does it only fail on 9x?

- Why does postgres use a fixed address at all, instead of using NULL to
   let the system decide which address to use?
