Upgrading your version of PostgreSQL to 8.1 will give you significant
benefits to performance.

You will need to attach the query.
EXPLAIN ANALYZE SELECT ...
where SELECT ... is your query. That will help us work out what the
problem is.
0.86 seconds might be slow for a query that returns 1 row, it might be
fast for a query that returns a large set with complex joins and where
conditions. Fast and slow are not objective terms. They are very
dependent on the query.

456,541 is not all that many records. But again you will need to post
more information for us to be able to assist.
