Actually, I think I suggested that you consult the pgsql-performance
archives, where this type of problem has been hashed out before.
See for instance this thread:
http://archives.postgresql.org/pgsql-performance/2004-07/msg00169.php
particularly
http://archives.postgresql.org/pgsql-performance/2004-07/msg00175.php
http://archives.postgresql.org/pgsql-performance/2004-07/msg00184.php
http://archives.postgresql.org/pgsql-performance/2004-07/msg00185.php
which show three different ways of getting the planner to do something
sane with an index range bound like "now() - interval".
