Hey Tom - 
Ran across this paper, about an interesting approach, pulling in the indices
to aid in selectivity estimates.

http://db.cs.berkeley.edu/papers/CSD-98-1021.pdf

I grabbed this from a link at:

while looking at the Mariposa work ( http://mariposa.cs.berkeley.edu)
from the Sequoia2000 project. I've convinced my team to let me spend
a couple days analyzing what it would take to fold the remote access
features of Mariposa into the current PostgreSQL tree.  I grabbed the
alpha-1 code (June 23, 1996) which seems to be based on an early version
of Postgres95. Interesting to see all the academic cruft you guys have
already cleaned out ;-)
