What platform are you on? From the above it sounds like Windows.

You might be able to do it as follows:

- Install Postgres on the second computer using a local path for the
data directory.
- Stop the database server.
- Restart it with the -D option pointing at the data directory on the
external drive.

Make sure that you use the same major version on both computers - e.g.
9.1, 9.0, etc.

I think this will work; though it's not something I personally would
do... it sounds a bit fragile.
