There is no way to say to use a specific index. You can turn off some plans
(and raise the cost of sequential scans, since that is sometimes the only
way to do something) or you can adjust the relative costs of such things
as cpu time and disk i/o. Making sure you have done an analyze and that
you have detailed enough statistics for the planner is also important.
P.S. You should keep replies on the list.
