You can have a look through all the release notes from 7.2.1 to current to see what will be fixed, including any data eating insects. Check this page http://www.postgresql.org/docs/7.4/static/release.html
Obviously you’ll need to test everything, but you should be able to install the new version, use pg_dumpall to dump your DB, and then restore it to the new version. Any errors that come up will need to be investigated…

Subject: [ADMIN] Upgrading from 7.2.1 to 8.x
Question,
I have an ancient database that is running Postgresql 7.2.1 on AIX. Is it safe to directly upgrade the database to 8.1? If not, what steps do I need to take?
I have been pushing for 3 years to upgrade this database, and with some upcoming projects, I am going to do another push with management to upgrade this database.
Also, I know there are a ton of fixes/improvements from 7.2, but are there any major data losing bugs in this version that I can use as added pressure on management?
Thanks,
Chris
