Hi,

For what it's worth, WindowsXP (at least) seems to currently support 
forward slashes at the OS level, so this Postgres behavior isn't as odd 
as it might seem. If you enclose your paths with double quote (") 
marks, Windows will even accept Unix style paths for some instructions 
on the command line:

dir "/temp"

Feeding Windows API calls with forward slashes seems to work with 
everything I've tried so far, so using them in Postgres seems perfectly 
smart, and reasonable..

Hope that helps,

Steve
