I meant I did Vacuum Analyze.
In any case, Aside from the vacuum analyze, I also tested it right after a database restore, so there should be no need for any maintenance features.

I just upgraded my database server from 8.0.1 to 8.2.4
Most things went very well, but I have a couple of queries that really slowed down with the new server.
On 8.0.1 the query took less then 3 seconds to complete. On 8.2.4 the same query
(I vacuumed the database before running the query) takes 60 seconds (10 minutes with Explain Analyze).
Did you analyze the 8.2 db? AFAIK a plain vacuum doesn't gather any statistics.
Kind regards,

choose an index scan if your joining column's datatypes do not
