Postgres 7.2 for Cygwin

I've taken over as admin on a W2K box which is running Postgres 7.2 under
Cygwin. However, there seems to be some cleaning up I need to do to get
things in order.

I don't want to upgrade to the latest version of Postgres (7.4.5) until I
can get the details of the current (7.2) installation sorted out.

Can anyone tell me how I can go about obtaining the old, 7.2 version of
Postgres to run on Cygwin? I don't see it in the Cygwin setup. I've
tried searching for:

postgresql-7.2.tar.bz2

but I've had no luck.

Any help would be appreciated.

Thanks,

Zeb
