Corinna,
I apologize for the delay, but I was on vacation...

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?
No.
Two questions come to mind:
- How does postgres evaluate that address
I don't know.
and why does it only fail on 9x?
Ditto.
- Why does postgres use a fixed address at all, instead of using NULL
to let the system decide which address to use?
Ditto.
I do not have access to Windows 9x and (unfortunately) have not used
PostgreSQL seriously for 3 years now, so I'm not particularly motivated
to work on this problem.
Sorry,
Jason

Neither the Cygwin nor the (beta) Windows-native version of Postgresql
is supported in any way on Windows 9x/ME AFIAK. Anyone trying to run
it there is strictly on their own.

According to the docs, even the 8.0 developer docs
(http://developer.postgresql.org/docs/postgres/install-win32.html),
"Tip: If you are using Windows 98 or newer you can build and use all of
PostgreSQL "the Unix way" if you install the Cygwin toolkit first. In
that case see Chapter 14."
I don't see any mention of XP, whether the Pro or Home version, will be
supported in version 8 at the moment either.
