Read the 8.0 release notes.

You are going to want to do a complete dump of your 7.2 databases while
the 7.2 server is running. (If you can, you should use the 8.0 version
of pg_dumpall.) Then once you have got the 8.0 server running, you will
need to reload the databases using psql or pg_restore (depending on which
options you used while running pg_dumpall).
