To expand on what Josh said, the expense in this case is development
resources. If you look on the developer site you'll see a huge TODO list
and a relatively small list of PostgreSQL developers. To develop a
cluster solution similar to RAC would probably take the efforts of the
entire development team for a year or more, during which time very
little else would be done.
I'm glad to see your persistance in wanting to use PostgreSQL, and there
might be some kind of limited clustering scheme that could be
implemented without a great amount of effort by the core developers. In
that case I think there's a good chance you could find people willing to
work on it.
