Seeing as I didn't write Windows or any of the plethora of anti-virus
software, no I really can't. It's unforgivable behaviour.
Can I provide evidence that it happens? Just read the archives of
this list for the evidence. I've seen it often enough to know that
most anti-virus software seems to open files in exclusive mode and
cause problems for postgresql, among other apps.

Because we've seen lots of problems with large shared buffers on windows here.
Now, maybe for a windows specific app it's all fine and dandy. but
for the way pgsql works, windows and large shared buffers don't seem
to get along.
I'm done. Use windows all you want. I'll stick to unix. It seems to
just work for pgsql.
