You're focusing on the indexes when the problem is dead table rows.
It's very hard to believe that there's any OS dependence as such
involved in that. I wonder whether (a) the Ubuntu and Fedora packages
you're using are the same 8.1.x point release; (b) if there's any
interesting non-default behavior built into the Ubuntu packaging
... like running autovacuum automatically, for instance.
