You aren't on windows, are you?
Having done this recently, go with the upgrade. You have to recompile
anyway, I think.

I typically just move the old pgsql directory to pgsql-8.0.0 (under
/usr/local, for example), do the reinstall of the upgrade, etc. I do a
dumpall from the old version before doing any of this and then rebuild
the database in the new installation, but I think I saw that you don't
need to do that for 8.0.0 to 8.0.2 (that the data directory structure,
etc. is the same), but you probably want to confirm that. If something
breaks, then you can just move the entire pgsql-8.0.0 directory back to
the old pgsql location and you are back to 8.0.0 again.
