Yeah, 32bit 2003 SP2, which has the same limits as XP. It looks like
Vista also has the same limits on actual heap sizes, but manages
kernel address space dynamically, so it doesn't get stuck with
arbitrary limits there. I don't have a Vista machine to verify
though.

Service, I've been using the standard MSI install of 8.2.5.

Well, the only thing actually running as a service is pg_ctl; the
other processes just belong to the same desktop. They're all console
executables, so they get the usual objects, but they're not visible
anywhere.
It could be that there's a significant difference between XP and 2003
in how that's handled though. I do have an XP SP2 machine here with
512MB RAM, and I'll try tests on it as soon as I can free up what it's
currently occupied with.
