Question about cygwin/postgres install

Hi,

I found a webpage www.postgresql.org/docs/faqs/text/FAQ_MSWIN that had How to install PostgreSQL on Windows.

I followed the directions and got cygwin working. I can do ls and all the unix commands. The problem is that it says:
Once the down load is complete, open a Cygwin shell and do the following:

Start ipc-daemon2 for shared memory support, by entering the command ipc-daemon2 & Unfortunately, bash cant find
this command. I cant either when I use windows explorer to search for it. I am pretty frustrated. The next steps tell how
to create a new database cluster using initdb and then the postmaster.... I see both of those in the bin directory.

Do you know where ipc-daemon2 is supposed to come from?

Thanks for any help you can provide.
Best Regards,

Sherry
