You can simply look at the release notes for 7.3, 7.4, 8.0, 8.1, and
8.2.

You can find them here:
  <http://www.postgresql.org/docs/8.2/static/release.html>

More specifically, you can find them at these URLs.

http://www.postgresql.org/docs/8.2/static/release-7-3.html
http://www.postgresql.org/docs/8.2/static/release-7-4.html
http://www.postgresql.org/docs/8.2/static/release-8-0.html
http://www.postgresql.org/docs/8.2/static/release-8-1.html
http://www.postgresql.org/docs/8.2/static/release-8-2.html

Print off the contents of those five URLs, and you'll find somewhere
between 40 and 50 pages worth of _brief listings_ of bug fixes and
enhancements.  Drop that pile of paper on his foot and ask if he
thinks it seems heavy enough to seem significant.

Add to that the other folks' arguments:

 - There be "database eating bugs" there that be fixed in later
   releases.
 - Nobody is interested in supporting problems you have with such an
   ancient version.
