Older versions

I installed Cygwin on my desktop long time ago. So, now I have old versions of different packages, such as PostgreSQL 7.3.4 set up on my desktop.

I am currently trying to set up my laptop and I want to have identical setup to my desctop. Which mean that I want an old version of PG.

So, my question is how to install old versions of Cygwin on my laptop that have old versions of Postgres on my laptop?

P.S. If somebody is interested why I need to install old versions of PosgreSQL on my Windows machine, it's because PgAdmin2 (old versions, which works with PostgreSQL 7.x) can import Access database, but not  PgAdmin3.

Regards.
