It might for 32-bit, but I'm pretty sure it's not going to for 64-bit
because Windows is LLP64 and Linux is LP64, so sizeof(long) differs. See
http://en.wikipedia.org/wiki/64-bit_computing .
(Yet another area where Windows is annoyingly and pointlessly different,
like use of UTF16 instead of UTF-8, though at least there they have the
excuse of doing it first.)
Just use a Linux box or a virtual machine to start a copy of the
database, then pg_dump -Fc it and pg_restore to a new instance on the
Windows box.
