OK, I have added this conversion scripts to CVS along with Thomas's. If
someone wants to merge them into one, feel free to submit a patch. I
have provided a URL to my2pg.pl to retrieve the most recent version.

The only license issue was that the bottom of the source code had a
mention referring to the GPL for more information. I removed that
because it now clearly states it has a BSD-like license.

Thanks.
