This is the wrong list for this question.
I recommend you read up on indexes and make some attempts at solving
the problem yourself. If you can't reach the level of performance you
expect, try to present a more specific question to pgsql-novice (if
it is about how indexes in PostgreSQL work in general) or
pgsql-performance (if you can't understand why a particular attempt
to solve the problem is not performing as well as you think it
should.
