May we know the postgres version that you are running and
see the query that run slow ?
Is also usefull take a look at your postgresql configuration.
You can see doing select * from pg_stat_activity the
queries that are currently running on your server, and
do a explain analize on it to see which one is the
bottleneck. If you are running the 7.4 you can see on
the log the total ammount for each query.
Let us know.
