[ADMIN] startup Postgres on NT

[wit]

Hello,

I download cygwin package, IPC package and postgres's binaries and install
them on NT.
I startup postgres with the following command:
   - open cygwin-shell
   - ipc-daemon&
   - postmaster -i -S
1. When I close cygwin-shell or I logout, postgres process will close too.
How to keep progres process running when I logout?
2. How to startup postgres with NT startup?

Regards,
wit
